Ab initio study of resonance states of exotic 10Li nucleus

Abstract

The spectrum, partial and total decay widths of the states of the exotic 10Li nucleus are studied in an ab initio approach. The spectrum is calculated using No-Core Shell Model and corresponding extrapolation procedure. The calculations use the well-proven Daejeon16 potential. The NCSM-based approach, which includes a method for constructing the basis of functions of cluster channels and a procedure for matching the cluster form factors obtained within this method with the asymptotic wave functions, is applied to compute the widths of the levels. The results obtained quite adequately reproduce the pattern given by the most advanced experiments. Detailed predictions of the spectral characteristics of 10Li nucleus states are given.
