S OF PAPERS PUBLISHED April 1, 2001 – March 31, 2002 Isoscalar Giant Resonances in Si and the Mass Dependence of Nuclear Compressibility D. H. Youngblood, Y. -W. Lui, and H. L. Clark Phys. Rev. C 65, 034302 (2002) The giant resonance region from 8 MeV<Ex<55 MeV in Si has been studied with inelastic scattering of 240 MeV α particles at small angles including 0°. Strength corresponding to 81±10%, 68±9%, and 15±4% of the isoscalar E0, E2, and E1 sum rules, respectively, was identified with centroids of 21.25±0.38 MeV, 18.54±0.25 MeV, 19.15±0.60 MeV, and rms widths of 6.4±0.6 MeV, 4.7±0.6 MeV, and 6.9±0.7 MeV. The mass dependence of the compression modulus of finite nuclei is shown to be reasonably well reproduced from A = 24 to 208 in relativistic mean field calculations with the NLC interaction having Knm= 225 MeV and in nonrelativistic calculations with the RATP interaction having Knm=240 MeV. Giant Resonances in O Y. W. Lui, H. L. Clark, and D. H. Youngblood Phys. Rev. C, 64, 064308 (2001) Giant resonances in O have been studied with inelastic scattering of 240 MeV α particles at small angles. Isoscalar E0, E1, and E2 strength corresponding to 48±10%, 32±7%, and 53±10%, of the respective energy-weighted sum rule was identified between Ex=11-40MeV with centroids of 21.13±0.49, 21.67±0.61, and 19.76±0.22 MeV and root-mean-square widths of 8.76±1.82, 7.10±0.52, and 5.11±0.17 MeV, respectively. Elastic scattering and inelastic scattering to states at 6.13, 6.92, and 11.52 MeV were measured from θc.m.=2.5° to 11.5°. Isoscalar EO, E1, and E2 Strength in Ca D. H. Youngblood, Y. -W. Lui, and H. L. Clark Phys. Rev. C, 63, 067301 (2001) The giant resonance region from 10<Ex<55 MeV in Ca has been studied with inelastic scattering of 240-MeV α particles at small angles including 0°. Strength corresponding to 97±11%, 108±12%, and 62 + 10-20% of the isoscalar E0, E2, and E1 sum rules, respectively, was identified with centroids of 19.18±0.37 MeV, 17.84±0.43 MeV, 23.36±0.70 MeV, and rms widths of 4.88±0.57 MeV, 2.89±0.60 MeV,
