The capture reaction can be divided into two parts, that is the compound and direct processes. For most stable nuclei, the compound process occupies a large part of the neutron capture cross section. However, it has been pointed out that the direct process comes to play a comparable role to the compound one at a low energy in light and neutron-rich nuclei, where the number of resonance state at the neutron threshold energy is relatively small. In addition, there is an interference term between the direct and compound processes. However, it is usually neglected for most nuclei, because either of the compound or the direct process is more important than the other, its contribution becomes negligible. However, some experiment data have given an implication of the existence of the interference effect, and Mengoni and Otsuka reported that the experimental results of capture cross section can be described by taking into account it. It is then natural as a next step to have a concern whether the interference effect comes to play a role for neutron-rich nuclei as well. We therefore calculate the neutron capture reaction for neutron-rich nuclei and study the interference effect on it. We will present some results for neutron-rich nuclei and the interference effect becomes important.

Effect of two-particle two-hole excitations in target nuclei on inelastic differential cross sections

Minato, Futoshi; Fukui, Tokuro*

no journal, , 

A picture of nuclear excited states can be discribed by 1p1h excitation. Experimental data of inelastic scatterings are reasonably reproduced theoretically in this picture. However, it is known that higher-order configurations are important for a better insight of the excited states. This may apply to the inelastic scattering. However, the relation between higher-order configuration and inelastic scattering is not clear. To clarify the relation, we consider 2p2h excitation of target nuclei and focus on the differential cross sections. The 2p2h states of target nuclei are calculated by SRPA. The reaction process is calculated by DWBA. As a reaction channel, inelastic scattering and (p,n) reaction are chosen. It turned out that the diffraction patterns of the differential cross section considering 2p2h were not significantly different from those considering 1p1h although the absolute values were smaller than 1p1h calculation. We discuss it from the nuclear structural point of view.
