Background-free inelastic scattering spectra have been obtained for the Sm isotopes with 400 MeV alpha particles at forward angles (including 0degrees) to investigate the effect of deformation on the compressional-mode giant resonances. The strength distributions for the isoscalar giant resonances (L < 3) have been extracted for the spherical nucleus Sm-144 and the deformed nucleus (SM)-S-154. We have observed that the effects of deformation are different for the low- and high-excitation-energy components of the isoscalar giant dipole resonance in Sm-154. Evidence for the theoretically predicted coupling between the isoscalar dipole resonance and the high-energy octupole resonance is reported. (C) 2002 Elsevier Science B.V. All rights reserved.

A new method, based on the excitation of the giant (spin-dipole) resonances in charge-exchange reactions, for studying the neutron-skin thickness has been tested. For a precise experimental test the (He-3,t) reaction on even Sn isotopes has been used. The results obtained are in good agreement with previous neutron-skin thickness values provided by other experimental and theoretical methods.

Distribution of the Gamow-Teller strength in Nb-90 and Bi-208

Publisher：AMER PHYSICAL SOC
The (He-3,t) charge-exchange reaction has been studied at E(He-3)=450 MeV and angles near 0 degrees on targets of Zr-90 and Pb-208. Fragmentation of the Gamow-Teller (GT) strength into separate components of the particle-hole type has been observed. The distribution of the GT strength in Nb-90 and in Bi-208 has been calculated within the continuum quasiparticle random phase approximation and continuum-random-phase approximation approaches, respectively. These components, especially in Pb-208, could be related with the direct, core polarization, and back-spin-flip Gamow-Teller strength.
