gogny hartree fock bogolyubov plus quasiparticle random phase approximation predictions of the m 1 strength function and its impact on radiative Neutron Capture cross section
Physical Review C, 2016Co-Authors: Stephane Goriely, Stephane Hilaire, Sophie Péru, M Martini, I Deloncle, Francois LechaftoisAbstract:Valuable theoretical predictions of nuclear dipole excitations in the whole chart are of great interest for different nuclear applications, including in particular nuclear astrophysics. Here we extend our large-scale calculations of the $E1 \ensuremath{\gamma}$-ray strength function, obtained in the framework of the axially- symmetric-deformed quasiparticle random phase approximation (QRPA) based on the finite-range D1M Gogny force, to the calculation of the $M1$ strength function. We compare our QRPA prediction of the $M1$ strength with available experimental data and show that a relatively good agreement is obtained provided the strength is shifted globally by about 2 MeV and increased by an empirical factor of 2. Predictions of the $M1$ strength function for spherical and deformed nuclei within the valley of $\ensuremath{\beta}$ stability as well as in the Neutron-rich region are discussed. Its impact on the radiative Neutron Capture cross section is also analyzed.

The Gogny-HFB+QRPA dipole strength function and its application to radiative Neutron Capture cross section
2017Co-Authors: Stephane Goriely, Stephane Hilaire, Sophie PéruAbstract:Valuable theoretical predictions of nuclear dipole excitations in the whole chart are of great interest for different nuclear applications, including in particular nuclear astrophysics. Here we extend our large-scale calculations of the E1 and M1 absorption γ-ray strength function obtained in the framework of the axially-symmetric deformed quasiparticle random phase approximation (QRPA) based on the finite-range D1M Gogny force to the determination of the de-excitation strength function. To do so, shell-model calculations of the de-excitation dipole strength function as well as experimental data are considered to provide insight in the low-energy limit and to complement the QRPA estimate phenomenologically. We compare our final prediction of the E1 and M1 strengths with available experimental data at low energies and show that a relatively good agreement can be obtained. Its impact on the average radiative width as well as radiative Neutron Capture cross section is discussed.
