Time-dependent Calculations for Two-proton Decay Width with Schematic Density-dependent Contact Pairing Interaction

Oishi Tomohiro^{1, 2}

摘要: We calculate the two-proton decay width of the 6Be nucleus employing the schematic densitydependent contact potential for the proton-proton pairing interaction. The decay width is calculated with a time-dependent method, in which the two-proton emission is described as a time-evolution of a threebody meta-stable state. Model-dependence of the two-proton decay width has been shown by comparing the results obtained with the two different pairing models, schematic density-dependent contact and Minnesota interactions, which have zero and finite ranges, respectively.
