interpretation of momentum distribution of Recoil Ions from laser induced nonsequential double ionization
Physical Review Letters, 2000Co-Authors: Andreas Becker, Farhard FaisalAbstract:: We show that the recently reported momentum distribution of Recoil Ions from laser induced nonsequential double ionization can be interpreted as a combined effect of interelectron correlation and final state field interaction ("Volkov dressing") of the two outgoing electrons. We also find a cutoff formula for the Recoil momentum that gives the maximum momenta observed in the experiments.

interpretation of momentum distribution of Recoil Ions from laser induced nonsequential double ionization by semiclassical rescattering model
Physical Review A, 2000Co-Authors: Jing Chen, Jie Liu, W ZhengAbstract:Using a semiclassical rescattering model, the momentum distribution of Recoil Ions from laser-induced nonsequential double ionization is obtained and the result is consistent with the experiment reported recently. We show that the characteristic double-hump structure of the Recoil momentum distribution of the ${\mathrm{He}}^{2+}$ ion parallel to the polarization axis is just the consequence of the rescattering dynamic of nonsequential double ionization and the acceleration of the Ions in the laser field.

β delayed neutron spectroscopy using trapped radioactive Ions
Physical Review Letters, 2013Co-Authors: N D Scielzo, R M Yee, P F Bertone, F Buchinger, S Caldwell, J A Clark, C M DeibelAbstract:A novel technique for beta-delayed neutron spectroscopy has been developed using trapped radioactive Ions. The neutron energy spectrum was reconstructed by measuring the time of flight (TOF) of the nuclear Recoil following neutron emission, thereby avoiding all the challenges associated with neutron detection such as backgrounds from scattered neutrons and gamma rays and complicated detector-response functIons. A proof-of-principle measurement was conducted on 137I+ by delivering Ions from a 252Cf source, confining them in a linear Paul trap surrounded by radiation detectors, and measuring the neutron energy spectrum and branching ratio by detecting the beta and Recoil Ions in coincidence. Systematic effects were explored by determining the branching ratio three ways. Improvements to achieve higher detection efficiency, better energy resolution, and a lower neutron energy threshold were implemented by upgrading the detectors and optimizing the trapping apparatus. These improvements were demonstrated in a campaign of measurements including 138I, which is a standard beta-delayed neutron precursor outlined by a recent IAEA report on delayed neutron measurements.
