Probing nuclear correlations by two proton emission
... We describe emission of two particles by solving the Schrödinger equation with 1) pairing two-proton wave function on the nuclear surface as an initial condition and 2) outgoing boundary conditions at large distance. The main purpose is: to investigate the dependence of the half-life versus the para ...
