Erratum: Investigation of the3/22−state ofLi9with microscopic structure and

Abstract

The low-lying states of the 9 Li nucleus are investigated with a unified framework of microscopic structure and reaction models. In the structure model, the wave function is fully antisymmetrized and the 9 Li nucleus is described as an α + t + n + n four-body system, and low-lying 1/2 − , 3/2 − , 5/2 − , and 7/2 − states are obtained by the stochastic multi-configuration mixing method. Using these wave functions, the quasi-elastic cross section at E/A = 60 MeV and the elastic and inelastic cross sections at E/A = 50 MeV on the 12 C target are calculated in the framework of the microscopic coupled channel (MCC) method. The characteristic inelastic angular distribution is seen in the 3/2 − 2 state, whose α+t cluster structure and valence neutron configurations are discussed in detail. We find the possibility of triaxial deformation and mixing of di-neutron components in the 9 Li nucleus.

Comparison Between 9Li And 10Be Nuclei from Viewpoint Of Nuclear Structure And Reaction

“…However, the sum of the transition strength for the 9 Li nucleus is larger than that for the 10 10 Be nucleus from the viewpoint of the microscopic cluster model as discussed in Ref. [4]. Therefore, the agreement of the transition strengths for the 9 Li and 10 Be nuclei is not important for the nuclear structure sense.…”

“…In terms of the cluster model, the 10 Be ( 9 Li) nucleus is described as the α + α(t) + n + n four-body systems, respectively [1,2,3,4]. Recently, their similarity has been discussed from the viewpoint of the nuclear structure as in Refs.…”

“…Recently, their similarity has been discussed from the viewpoint of the nuclear structure as in Refs. [4,5,6,7]. However, their similarity is not investigated from the viewpoint of the nuclear reaction, although numerous observations are obtained through the nuclear reaction experiments.…”

Drastic change in inelastic scattering depending on the development of dineutron correlation in $^{10}$Be

“…By folding the effective nucleon-nucleon (NN) interaction with the projectile and/or target densities, the potential between projectile and target particles is obtained. The reliable and precise information is extracted from the experimental data by the development of the folding procedure and the effective NN interaction [34,43]. Recently, the characteristic behaviors of the cross section caused by the exotic structure and the property of the potential are predicted [43][44][45][46].…”
