S. Misicu et N. Carjan, PROTON DECAY FROM EXCITED-STATES IN SPHERICAL NUCLEI, Journal of physics. G, Nuclear and particle physics, 24(9), 1998, pp. 1745-1755
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 Pb-208 from excited states with
non-vanishing angular momentum l. Several quantities of interest in th
is process such as the decay rate lambda, the period of oscillation T-
osc, the transient time t(mu-), the tunnelling time tl,, and the avera
ge value of the proton packet position r(av) are computed and compared
with the WKB results.
