Abstract:

Based on a single-particle model which describes the time evolution of the wavefunction during tunnelling across a one-dimensional potential barrier we study the proton decay of from excited states with non-vanishing angular momentum . Several quantities of interest in this process such as the decay rate , the period of oscillation , the transient time , the tunnelling time and the average value of the proton packet position are computed and compared with the WKB results.
