Giant resonances in 116 Sn from 240 MeV 6 Li scattering
نویسنده
چکیده
Giant resonances in 116Sn were measured by inelastic scattering of 6Li ions at E6Li = 240 MeV over the angle range 0◦–6◦. Isoscalar E0–E3 strength distributions were obtained with a double folding model analysis. A total of 106+27 −11% of the E0 EWSR was found in the excitation energy range from 8 MeV to 30 MeV with a centroid (m1/m0) energy 15.39 +0.35 −0.20 MeV in agreement with results obtained with α inelastic scattering.

متن کاملCompression mode giant resonances
Compression mode giant resonances have been measured in many nuclei from C to Pb with inelastic scattering of 240 MeV particles at small angles. Isoscalar monopole distributions have been extracted for 17 nuclei and isoscalar dipole distributions extracted for 11 nuclei. The E0 strength distributions in Zr, Sn, Sm and Pb have been measured precisely and in Sn, Sm and Pb were found to be concent...
متن کاملCoulomb and nuclear excitation of giant dipole resonances in (a,a') inelastic scattering
Cross sections of inelastic a-particle scattering to isovector giant dipole resonances are calculated including both nuclear and Coulomb excitation. It is shown that the calculated cross sections are rather small and can be safely neglected for bombarding energies less than 200 MeV in determining the strength of the giant monopole resonance. This conclusion contradicts that of a recent report m...
متن کاملGiant Dipole Resonance Built on Highly Excited States of 120Sn Nuclei Populated by Inelastic a Scattering
High energy g rays from the decay of the giant resonance in hot Sn nuclei were measured in the excitation energy range of 30–130 MeV. The excited nuclei were populated by inelastic scattering of a particles at 40 and 50 MeVynucleon. The resonance width was observed to increase monotonically with increasing excitation energy, from 5 MeV at the ground state to ,12 MeV at the largest excitation en...
