Beta-decay and electron capture rates of hot nuclei in stellar matter

GT strength distributions along with β−-decay and electron capture rates are studied for the case of hot nuclei 78Ni embedded in matter at presupernova conditions. Calculations are performed using the self-consistent Skyrme-RPA approach extended to finite temperatures. Skyrme interaction parametriza...

Description
Summary:GT strength distributions along with β−-decay and electron capture rates are studied for the case of hot nuclei 78Ni embedded in matter at presupernova conditions. Calculations are performed using the self-consistent Skyrme-RPA approach extended to finite temperatures. Skyrme interaction parametrizations with and without tensor forces are used in order to analyze the role of tensor interaction and thermal effects on weak-interaction rates in hot nuclei.
