(AMER PHYSICAL SOC, 2011-09-14)Microscopic optical model potentials, based on density-dependent effective interactions, involve multidimensional integrals to account for the full Fermi motion of the target struck nucleon throughout the nucleus. If a ...
-
(Springer, 2017)An analysis of neutron and proton scattering off 40,48Ca has been carried out. Real and imaginary potentials have been generated using the Nuclear Structure Method (NSM) for scattering with the Gogny D1S nucleon-nucleon ...
-
Comparison of nucleon-nucleon potential models in a full-folding description of elastic scattering (1991-04)The sensitivity of proton-nucleus elastic scattering to different nucleon-nucleon effective interactions is studied within the framework of the nonrelativistic full-folding model. Calculations of the nucleon-nucleus ...

(1994-11)We investigate the role of the full dynamical dependence of the free off-shell nucleon-nucleon t matrix on the optical potential for proton-nucleus elastic scattering in the 100—400 MeV incident energy range within a ...
-
(Springer, 2016)We investigate homogeneous nuclear matter within the Brueckner-Hartree-Fock (BHF) approach in the limits of isospin-symmetric nuclear matter (SNM) as well as pure neutron matter at zero temperature. The study is based on ...
-
(Elsevier, 2017)We present a methodology to obtain the energy distribution of the neutron flux of an experimental nuclear reactor, using multi-foil activation measurements and the Expectation Maximization unfolding algorithm, which is ...
-
(2002)The nonrelativistic full-folding optical model approach for nucleon-nucleus scattering is extended into the relativistic regime. In doing so, kinematical issues involving the off-shell Lorentz boost of the colliding particles ...
-
(2007)By examining the structure in momentum and coordinate space of a two-body interaction spherically symmetric in its local coordinate, we demonstrate that it can be disentangled into two distinctive contributions. One of ...
-
(2007)A microscopic description of the quasielastic (p,n) charge-exchange reaction (here, charge-exchange scattering between analog states) is presented and discussed. Emphasis is focused on the spin-isospin structure of the ...
-
(AMERICAN PHYSICAL SOC, 1995-07)We develop an approach for incorporating both medium and off-shell effects in the calculation of full-folding nucleon-nucleus optical potentials for elastic scattering. The approach is based on a flexible scheme for ...
-
(Springer, 2015)The effect of in-medium dinucleon bound states on self-consistent single-particle fields in Brueckner, Bethe and Goldstone theory is investigated in symmetric nuclear matter at zero temperature. To this end, dinucleon bound ...

(2005)We investigate K +-nucleus elastic scattering at intermediate energies within a microscopic optical model approach using the current K +-nucleon (KN) phase shifts from the Center for Nuclear Studies of the George Washington ...
-
(American Physical Society, 2015)We present a nucleon elastic scattering calculation based on Green’s function formalism in the random-phase approximation. For the first time, the finite-range Gogny effective interaction is used consistently throughout the ...
-
(1990)Nonrelativistic full-folding optical model potentials for nucleon elastic scattering have been calculated and applied to proton scattering on ' 0 and Ca at energies between 135 and 500 MeV. The optical potentials were ...

(ELSEVIER SCIENCE BV, 2005-06-13)Neutron and proton densities in the nuclear periphery are investigated within (p,n) charge-exchange isobar transitions. For this purpose we have developed parameter-free optical potentials (1)) with a detailed treatment ...
-
(Springer, 2015)We present our current studies and future plans on microscopic potential based on effective nucleon-nucleon interaction and many-body theory. This framework treats in an unified way nuclear structure and reaction. It offers ...
-
(2007)Reaction cross sections for proton-nucleus elastic scattering are investigated within a nonrelativistic microscopic approach for the nucleon-nucleus optical model potential. Applications were made for nucleon energy ...
-
(1990-08)A framework based on a full-folding model of the nucleon optical potential is presented for studying nuclear densities of closed-shell nuclei using intermediate energy nucleon scattering. Using a density-matrix expansion ...
-
(AMERICAN PHYSICAL SOC, 1996-11)The sensitivity of nucleon-nucleus elastic scattering to the off-shell behavior of realistic nucleon-nucleon interactions is investigated when on-shell equivalent nucleon-nucleon potentials are used. The study is based on ...
