Measurement of alpha elastic scattering on <sup>104,106,108</sup>Pd at E<sub>α</sub>=386 MeV

POSTER

Abstract

We conducted measurements of elastic and inelastic scattering of 386 MeV alpha particles off the 104,106,108Pd isotopes to investigate the isoscalar giant monopole resonance. The experiment was carried out at the Research Center for Nuclear Physics, Osaka University. The alpha particles were accelerated to 386 MeV using the AVF cyclotron and the ring cyclotron and bombarded on the target in the scattering chamber. The scattered alpha particles were analyzed using the high-resolution magnetic spectrometer Grand Raiden, and subsequently detected by multi-wire drift chambers and two plastic scintillators.

We plan to analyze the obtained differential scattering cross-sections using the distorted-wave Born approximation calculations to examine the giant resonances in palladium isotopes. For this analysis, we need the optical-model potential for the elastic scattering between the incident alpha particle and target nuclei. To obtain this optical-model potential, we used the single-folding model where the effective interaction between the alpha particle and nucleons in palladium nuclei was convoluted with the nucleon density distribution calculated by the relativistic mean-field theory. We optimized the parameters of the effective interaction to reproduce the measured cross section for the elastic alpha scattering from each palladium isotope. The resulting effective interactions were then compared among the palladium isotopes.
