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.

The isoscalar giant monopole resonances (ISGMRs) in 90,92,94 Zr and 92,96,98,100 Mo have been studied with inelastic scattering of 240-MeV α particles at small angles including 0 o . Strength corresponding to approximately 100% of the ISGMR (E0) energy-weighted sum rule was identified in each nucleus. In all cases the strength consisted of two components separated by 7-9 MeV. Except for the mass 92 nuclei, the upper component contained 14-22% of the E0 energy-weighted sum rule (EWSR); however 38% and 65% of the E0 EWSR were located in the upper components in 92 Zr and 92 Mo, respectively. The energies of the ISGMRs for 92 Zr and 92 Mo are 1.22 and 2.80 MeV, respectively, higher than for 90 Zr, suggesting a significant nuclear structure contribution to the energy of the ISGMR in these nuclei. This has a large effect on the compression modulus of the nucleus with the values extracted for 92 Zr and 92 Mo being 27 and 56 MeV, respectively, higher than that for 90 Zr.

Isoscalar giant resonances in 90,92,94 Zr have been studied with inelastic scattering of 240 MeV α particles at small angles including 0 o . A significant fraction of the EWSR was found for isoscalar E0 (106%,103%,106%), E1 (64%,53%,96%), E2 (92%,93%,67%) and high energy octupole E3 (59%,69%,58%) resonances in 90,92,94 Zr respectively. Hartree-Fock-RPA calculations were made for each multipole using the KDE0v1 Skyrme-type effective nucleon-nucleon interaction and the results are compared to the experimental distributions.

Isoscalar giant resonances in 44 Ca have been studied with inelastic scattering of 240 MeV α particles at small angles including 0°. A majority of the Energy Weighted Sum Rule was identified for E0 and E2 (≈70%), and nearly half was identified for E1. The strength distributions are compared with the predictions from Hartree-Fock based Random Phase Approximation calculations with the KDE0v1 Skyrme-type interaction. The GMR energy moments for 40,44,48 Ca increase with mass, contrary to what would be expected with a negative symmetry energy, K τ .

Elastic and inelastic scattering of 240-MeV 6 Li particles from 58 Ni and 90 Zr were measured with the multipoledipole-multipole spectrometer from 4• θ c.m. 43• . The elastic scattering data were fitted with the doublefolding model using the density-dependent M3Y NN effective interaction and with a phenomenological WoodsSaxon potential. B(E2) and B(E3) values obtained for low-lying 2 + and 3 − states with the double-folding calculations agreed with the adopted values.
