Abstract
Based on a single particle model which describes the time evolution of the wave function during tunneling across a one dimensional potential barrier we study the proton decay of
208
Pb from excited states with non-vanishing angular momentum
ℓ
. Several quantities of interest in this process like the decay rate
λ
, the period of oscillation
T
osc
, the transient time
t
tr
, the tunneling time
t
tun
and the average value of the proton packet position
r
av
are computed and compared with the WKB results.
