Abstract
Decay widths in emission processes are described within the stationary scattering theory. We use a pocket-like potential between emitted fragments, centered on the nuclear surface. This picture predicts a linear dependence between the logaritm of the reduced width and fragmentation potential. It turns out that this law is satisfied by proton emission, alpha-decay and heavy cluster emission processes. In particular, we show that, by using surface Gaussian-like components in single particle orbitals mocking four body correlations, it becomes possible to enhance both electromagnetic and α transition probabilities up to the experimental values in 212Po.
