Microscopic optical potentials for nucleon - nucleus scattering
Microscopic optical potentials for nucleon-nucleus (NA) scattering obtained from the folding of the effective g matrices, solutions of the Bruckner-BetheGoldstone equation, with the densities of the target, are applied to the case of neutron-nucleus scattering. Given that the optical potentials are specified in all two-body angular momentum, spin and isospin channels available to the NA scatter...
متن کاملMicroscopic Optical Potentials for Elastic Nucleon-Nucleus Scattering
The theoretical approach to the elastic scattering of a nucleon from a nucleus, pioneered by Watson [1], made familiar by Kerman, McManus, and Thaler (KMT) [2] and further developed as the spectator expansion [3, 4, 5, 6] is now being applied with striking success. In a similar vein, a slightly di erent approach to the multiple scattering expansion within the KMT framework is being pursued by t...
متن کاملMicroscopic analysis of nucleus-nucleus elastic scattering at intermediate energies
2014 An effective nucleon-nucleon amplitude for bound nucleons taking into account medium effects such as Fermi motion and Pauli blocking has been derived from the Bethe-Goldstone equation, using a MonteCarlo simulation of a nucleon-nucleon collision in the nuclear medium. The obtained amplitude is local and density dependent. This amplitude has been used in a local density approximation to ana...
متن کاملComparison of Dirac and microscopic Schrödinger optical model potentials for nucleon - nucleus scattering
Detailed comparisons are made between results of calculations for intermediate energy nucleon– 208 Pb scattering using optical potentials obtained from Dirac phenomenology and a microscopic Schrödinger model. The two approaches yield quite similar results for all of the observables with each projectile , including spin observables, suggesting the two models are physically equivalent. A new phen...
متن کاملMicroscopic approach to pion-nucleus dynamics.
Elastic scattering of pions from finite nuclei is investigated utilizing a contemporary, momentum–space first–order optical potential combined with microscopic estimates of second–order corrections. The calculation of the first–order potential includes: (1) full Fermi–averaging integration including both the delta propagation and the intrinsic nonlocalities in the π-N amplitude, (2) fully covar...
