Isospin dependent nucleon-nucleus optical potential with Skyrme interactions

“…The comparison of calculated results of proton reaction cross sections with experimental data [58][59][60][61][62][63] for 27 Al is given in Fig. 10.…”

Reaction cross sections for 75–190 MeV alpha particles on targets fromC12toAuce1, Carlson2, Cox3 et al. 1994Phys. Rev. C

“…At present, the most scient method to measure reaction cross sections in this energy region is based on the attenuation technique as proposed by Gooding and Eisberg [15] and later modified by Gooding [16] and by Wilkins and Igo [17]. This method has been further improved and successfully used in a number of proton reaction cross section experiments by members of the present group [18], and the same technique is also applied in the alpha particle experiment reported here.…”

Comparison of optical model results from a microscopic Schrödinger approach to nucleon-nucleus elastic scattering with those from a global Dirac phenomenology

“…Although experimental data exist to much lower energies, any effective mean field prescription for the optical potential at such low energies is not appropriate. However, in a recent paper [52], a multi-channel algebraic scattering (MCAS) theory has been developed with which the low [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43] 16 O [44], [40], [45] 40 Ca [34], [46], [38], [47], [45], [43] 90 Zr [48], [38], [49], [39] 208 Pb [30], [32], [33], [35], [46], [50], [38], [39], [40], [51], [45], [43] -0 energy range should be covered. This MCAS approach lends itself to specification of the dynamic polarization potential resulting from a summation over all diverse channel functions allowed in that theory.…”

“…The global DP approach, based on the relativistic impulse approximation (RIA), fits the data well when proton and neutron densities, their root-mean-square radii, and the neutron skin thickness, all are credible. Targets of 40 Ca, 48 Ca and 208 Pb were considered [9]. However, the two models fundamentally are different.…”
