| Resumo | |
Inelastic Li-6 scattering at 100 MeV/u on C-12 and Nb-93 has been measured with the high-resolution magnetic spectrometer Grand Raiden. The magnetic-rigidity settings of the spectrometer covered excitation energies from 10 to 40 MeV and scattering angles in the range 0 degrees < theta(lab). < 2 degrees. The isoscalar giant monopole resonance was selectively excited in the present data. Measurements free of instrumental background and the very favorable resonance-to-continuum ratio of Li-6 scattering allowed for precise determination of the E0 strengths in C-12 and Nb-93. It was found that the monopole strength in C-12 exhausts 52 +/- 3(()(stat)(.)) +/- 8((sys.))% of the energy-weighted sum rule (EWSR), which is considerably higher than results from previous alpha-scattering experiments. The monopole strength in Nb-93 exhausts 92 +/- 4(()(stat)(.)) +/- 10((sys.))% of the EWSR, and it is consistent with measurements of nuclei with mass number of A approximate to 90. Such comparison indicates that the isoscalar giant monopole resonance distributions in these nuclei are very similar, and no influence due to nuclear structure was observed. (AU) | |
