Low-lying spectra of {sup 9}{Lambda}Be and {sup 9}Be within three-cluster model
- North Carolina Central University, 1801 Fayetteville Street, Durham, NC 27707 (United States)
An {alpha}-cluster model is applied to study the low-lying spectra of the {sup 9}{Lambda}Be and {sup 9}Be nuclei. The {alpha}{alpha}{Lambda} and {alpha}{alpha}n three-body problems are numerically solved by the Faddeev equations in configuration space using phenomenological pair potentials with spin-orbital {alpha}{Lambda} and {alpha}n interactions taken into account. For the {sup 9}{Lambda}Be hypernucleus we found a set of the potentials that reproduces the experimental data for the ground state (1/2 {sup +}) binding energy and excitation energy of the 5/2{sup +} and 3/2 {sup +} states, simultaneously. The LS coupling scheme is used for partial wave analysis. The total orbital momentum is fixed for each energy level. Under this assumption we calculated the {sup 9}Be spectrum within {alpha}{alpha}n model. The experiential data are well reproduced by the model, when a new classification for low-lying levels of {sup 9}Be as members of spin-flip doublets is applied.
