Dirac coupled channel analyses of 800 MeV proton inelastic scattering from24Mg

Neutron densities from a global analysis of medium-energy proton-nucleus elastic scattering

“…For a number of years we have used the relativistic impulse approximation (RIA) in the analysis of proton-nucleus elastic and inelastic scattering [16,17,18,19,20,21,22,23] and the RIA-KDP(Kemmer-Duffin-Petiau) [24,25,26] for meson-nucleus elastic scattering [27,28,29,30,31]. These approaches produce relativistic optical potentials which result in good agreement with medium-energy scattering observables.…”

Dirac coupled channel analyses of proton inelastic scattering from the 40Ar nucleus

“…The Dirac coupled channel equations are solved numerically using the computer code ECIS [16] which employs the sequential iteration method. We consider both the couplings between the 0 deformed nuclei [10][11][12][13]. This is not the case for the spherically-symmetric nuclei, where the excited states are well described by considering the coupling via single-step transitions [2,3].…”

“…Relativistic approaches based on the Dirac equation as the relevant wave equation have proved to be very successful in treating the proton elastic and inelastic scatterings at intermediate energies from the spherically symmetric nuclei [1][2][3][4] and a few deformed nuclei [5][6][7][8][9][10][11][12]. Considerable improvements have been shown in the coupled channel calculations using the Dirac phenomenology compared to the classical nonrelativistic calculations based on the Schrödinger equation [8][9][10][11][12][13].…”

Relativistic Dirac analyses of polarized proton scatterings to the 2+ gamma vibrational band in 24Mg and 26Mg

“…Because the Dirac analyses have proven to be very successful in describing the intermediate-energy proton elastic scatterings from the spherically symmetric nuclei and a few deformed nuclei [3][4][5][6], the relativistic approaches based on the Dirac equation are expanded to inelastic scatterings and have shown considerable improvements compared to the conventional nonrelativistic calculations based on the Schrödinger equation [7][8][9][10]. The relativistic effect is taken into account at the level of the kinemat- time-like vector potentials are considered.…”
