SCATTERING PHASE SHIFTS OF LITHIUM ISOTOPES

Source abstract

Scattering phase shifts on negative and positive parity states of 5Li, 6Li and 7Li nuclei are calculated applying two-body a+p, a+d and a+t systems and the complex scaling method. 6Li and 7Li are stable nuclei and their ground and low-lying excited states are considered in this work. In this study, we calculated scattering phase shifts of the negative parity J^pi=3/2-, and 1/2+ states for p-wave 5Li, J^pi=7/2-, 5/2-, 3/-2 and 1/2− states for p- and f-waves of 7Li and the positive parity J^pi=1+, 2+, 3+ states for s- and d-waves of 6Li.
