  • Parity-violating Electron Scattering
    Nuclear Physics A, 1997
    Co-Authors: T.w. Donnelly
    Abstract:

    Abstract The basic features of parity-violating Electron Scattering from the proton and from nuclei are summarized. References are given to the current literature where details of the discussions may be found.

  • The interpretation of parity-violating Electron-Scattering experiments
    Nuclear Physics A, 1992
    Co-Authors: M.j. Musolf, T.w. Donnelly
    Abstract:

    Abstract The theoretical interpretation of several prospective intermediate-energy parity-violating (p.v.) Electron-Scattering experiments is discussed. Particular attention is paid to the interplay of various sources of theoretical hadronic-physics uncertainties. It is argued that these uncertainties may render high-precision, p.v. Electron Scattering less suitable for standard-model tests than atomic parity-violation experiments. However, p.v. Electron Scattering offers a unique window on various aspects of nucleon and nullear structure, such as the presense of strange quarks in the nucleon. In particular, it is found that a series of measurements on the protoon could provide interesting constraints on the two strangeness vector-current form factors, although not to the degree needed to permit a 1% extraction of the weak mixing angle. The prospects for further tightening these constraints with elastic Scattering from the ( J π , T ) = ( o + , 0) targets and from the deuteron are evaluated in detail. Associated, unresolved theoretical issues are highlighted, and the relationship between theoretical interpretability and experimental doability is analyzed. These considerations are applied to three recent proposals for experiments at CEBAF. A treatment of quasielastic p.v. Electron Scattering is also given, including a reanalysis of the recent Mainz 9 Be( e , e′) measurement to account for radiative-correction uncertainties in the quoted value of the weak mixing angle. For each case considered, the kinematic conditions are identified for which interpretability of a prospective experiment might be optimized.

  • Electron Scattering for exotic nuclei
    Pramana, 2014
    Co-Authors: Toshimi Suda
    Abstract:

    A brand-new Electron Scattering facility, the SCRIT Electron Scattering Facility, will soon start its operation at RIKEN RI Beam Factory, Japan. This is the world’s first Electron Scattering facility dedicated to the structure studies of short-lived nuclei. The goal of this facility is to determine the charge density distributions of short-lived exotic nuclei by elastic Electron Scattering. The first collision between Electrons and exotic nuclei will be observed in the year 2014.

  • Nuclear physics at the SCRIT Electron Scattering facility
    Progress of Theoretical and Experimental Physics, 2012
    Co-Authors: Toshimi Suda, Tatsuya Adachi, Tatsuya Amagai, A. Enokizono, Masahiro Hara, T. Hori, Shin-ichi Ichikawa, Kazuyoshi Kurita, Takaya Miyamoto, Ryo Ogawara
    Abstract:

    The SCRIT Electron Scattering facility is under construction at the RIKEN RI Beam Factory. This is the worlds first facility dedicated to the study of the structure of short-lived nuclei by Electron Scattering, which has been a long-standing dream for nuclear physics. A novel Self-Confining RI Target (SCRIT) technique makes this challenging research possible. A series of test experiments using stable nuclei performed at this partially completed facility show that the collision luminosity between Electron beam and target nucleus reaches 10^27cm^-'2s^-'1, which is required for an elastic Electron Scattering measurement to determine the charge density distribution of the target nucleus. The first Electron Scattering for unstable Sn isotopes will take place in the year 2014. Nuclear Physics at the SCRIT Electron Scattering Facility

  • Structure studies of unstable nuclei by Electron Scattering
    Progress in Particle and Nuclear Physics, 2005
    Co-Authors: Toshimi Suda, Masanori Wakasugi
    Abstract:

    Abstract Electron Scattering provides essential information on the internal structure of atomic nuclei. A new scheme, SCRIT (Self Confining Radioactive Isotope Target), is proposed to study the internal structure of short-lived unstable nuclei by Electron Scattering. A numerical simulation shows that SCRIT provides a sufficiently high luminosity for Electron-Scattering experiments to measure the charge form factor. A feasibility study of this new scheme is now underway at an existing Electron storage ring.

  • Structure Studies of Unstable Nuclei by Electron Scattering
    AIP Conference Proceedings, 2005
    Co-Authors: Toshimi Suda
    Abstract:

    Electron Scattering provides essential information on the internal structure of atomic nuclei. A new scheme, SCRIT(S_elf‐C_onfining R_adioactive I_sotope T_arget), is proposed to study the internal structure of short‐lived nuclei by Electron Scattering. Numerical simulations reveal that SCRIT provides high enough luminosity to determine the charge form factor by elastic Scattering. A feasibility study of this novel scheme is now underway at an existing Electron storage ring.

  • Total Electron-Scattering cross sections of pyrimidine
    Physical Review A, 2013
    Co-Authors: Woon Yong Baek, A. Arndt, Hans Rabus, Mingjie Wang
    Abstract:

    Total Electron-Scattering cross sections of pyrimidine, the basic component for the nucleic bases cytosine and thymine, were measured for Electron energies from 5 eV to 1 keV using the linear transmission method. The measured results were compared to semiempirical data obtained by means of the additivity rule and to experimental data for benzene since it has a similar ring structure and the same number of valence Electrons as pyrimidine. Furthermore, integral elastic and inelastic Electron-Scattering cross sections of pyrimidine were calculated by applying the spherical complex optical potential model. The sum of both cross sections agrees reasonably well with the experimental total Electron-Scattering cross sections of pyrimidine in the energy range from 20 eV to 1 keV. The experimental data are, however, significantly lower than the theoretical cross sections when including the contribution of rotational excitations to the Electron Scattering.

  • Total Electron Scattering cross section for Cl2
    The Journal of Chemical Physics, 1999
    Co-Authors: Gary D. Cooper, Jason E. Sanabia, John H. Moore, James K. Olthoff, Loucas G. Christophorou
    Abstract:

    Absolute measurements of the total Electron Scattering cross section, σsc,t(e), for chlorine, Cl2, are reported for Electron energies, e, ranging from 0.3 to 23 eV. The present data are in reasonable agreement with previous measurements of the cross sections for total Electron Scattering and total rotational excitation, and indicate significant indirect vibrational excitation due to negative ion resonances.
