“…On the other hand a great success has been achieved in deriving DOM potentials for nucleon scattering on closed shell nuclei like 40 Ca [4,[11][12][13][14], 90 Zr [14][15][16][17][18] and 208 Pb [1][2][3][4]11,12,19,20], for which experimental information on bound-states is available. Many studies have dealed also with neutron scattering on non magic nuclei( 39 K [21], 51 V [22], 86 Kr [23], 89 Y [24], 93 Nb [25], 113 In [26] and 209 Bi [20,27,28]). However very few studies have been devoted to DOM potentials for nuclei with A 30.…”

Dispersive spherical optical model of neutron scattering from27Alup to 250 MeV

et al. 2002

A spherical optical model potential ͑OMP͒ containing a dispersive term is used to fit the available experimental database of () and T for nϩ 27 Al covering the energy range 0.1-250 MeV using relativistic kinematics and a relativistic extension of the Schrödinger equation. A dispersive OMP with parameters that show a smooth energy dependence and an energy-independent geometry are determined from fits to the entire data set. A very good overall agreement between experimental data and predictions is achieved up to 150 MeV. Inclusion of nonlocality effects in the absorptive volume potential allows one to achieve an excellent agreement up to 250 MeV.

Proton−90Zr mean field between -60 and +185 MeV from a dispersive optical model analysis

et al. 1993

Elastic scattering of protons from Zr in the energy range E~= 9.8 to 135 MeV is analyzed using a dispersive optical model potential (OMP). In this analysis, a dispersion relation connects the volume integrals of the imaginary and the real parts of the OMP. Best-fit dispersive OMP parameters are obtained from fits to experimental cross section and analyzing power data at each energy, while the volume integrals of the imaginary potential and dispersive correction terms are fixed at the empirical values obtained in the individual proton elastic scattering analyses from 9.8 to 135 MeV. Predictions of the cross section and analyzing power angular distributions from the best-fit dispersive OMP and conventional OMP are obtained, and give similar quality fits to data. A dispersive OMP with parameters that show a smooth energy dependence are determined from fits to the entire data set. Comparison of cross sections and analyzing powers calculated by the dispersive OMP with experimental data at 160 and 185 MeV is also presented. The dispersive OMP with a smooth energy dependence is extended to the negative energy region with the guidance of the known first single-particle and single-hole state energies near the Fermi energy, EF = -6.8 MeV, to provide parameters for the shell model potential. This analysis also provides estimates for single-particle and hole energies E"», root-mean-square radii R"l,, expectation values of the effective mass (m */m ) "I,, occupation probabilities X"&,, absolute spectroscopic factors S"l,, and spectral functions g"&, (E") for proton single-particle and single-hole orbits in Zr. These estimates are compared with available experimental information.PACS number(s): 24. 10.Ht, 24.70.+s, 25.40.Cm

“…For the fast energy region, the measurements performed by Das et al [Das and Finlay, 1990] and Finlay et al [Finlay et al, 1993] Figure 35 shows that JEFF-3.3T1 overestimates the total cross section (underestimates the transmission) in the RRR (up to 100 keV) and has a clearly unphysical cross section shape from 100 to 250…”
