The giant resonance region from 9.5 MeV < E x < 40 MeV in 48 Ca has been studied with inelastic scattering of 240 MeV α particles at small angles, including 0º. 95±11% of E0 energy weighted sum rule (EWSR), 10 16 83 + − % of E2 EWSR and 137±20% of E1 EWSR were located below E x = 40 MeV. A comparison of the experimental data with calculated results for the isoscalar giant monopole resonance, obtained within the mean-field based random phase approximation, is also given.

“…3. The extracted B(EL) values for the 2 + and 3 -states are listed in Table II and compared to the values from other measurements [31][32][33][34][35][36]. The B(E2) value for the 3.832 MeV 2 + state is consistent with the recent measurement using 6 Li inelastic scattering [31] and is within the errors of the adopted value [32].…”

“…The OM description of the elastic proton scattering from 48 Ca, 90 Zr, 120 Sn, and 208 Pb targets at incident proton energy of 40 MeV given by the three global proton-nucleus OP's are shown in Fig. 1 together with the measured data [34,35]. Except for some underestimation of the calculated elastic cross section in the p+ 48 Ca case, the overall OM description of the considered elastic scattering data is reasonable.…”

“…7. A good description of the measured elastic proton scattering data [34,35] can be reached after the complex folded potential is renormalized by N V ≈ 0.90-0.94 and N W ≈ 0.6-0.8. The OM results obtained for the elastic neutron scattering are shown in Fig.…”

A consistent folding model analysis of the ( S = 0, T = 1) charge exchange (p, n) reaction measured with 48 Ca, 90 Zr, 120 Sn, and 208 Pb targets at the proton energies of 35 and 45 MeV is done within a two-channel coupling formalism. The nuclear ground state densities given by the Hartree-Fock-Bogoliubov formalism and the density-dependent CDM3Y6 interaction were used as inputs for the folding calculation of the nucleon optical potential and (p, n) form factor. To have an accurate isospin dependence of the interaction, a complex isovector density dependence of the CDM3Y6 interaction has been carefully calibrated against the microscopic Brueckner-Hartree-Fock calculation by Jeukenne, Lejeune, and Mahaux before being used as folding input. Since the isovector coupling was used to explicitly link the isovector part of the nucleon optical potential to the cross section of the (p, n) reaction exciting the 0 + isobaric analog states in 48 Sc, 90 Nb, 120 Sb, and 208 Bi, the newly parametrized isovector density dependence could be well tested in the folding model analysis of the (p, n) reaction. The isospin-and density-dependent CDM3Y6 interaction was further used in the Hartree-Fock calculation of asymmetric nuclear matter, and a realistic estimation of the nuclear symmetry energy was made.
