Probing nuclear mean field by proton emission

• We show that proton emission is a valuable tool to investigate mean field properties of exotic proton rich nuclei. We give a formula that relates the logarithm of the half-life, corrected by the centrifugal barrier, with the Somerfeld parameter in proton decay processes. The corresponding experimental data lie on two straigth lines which appear as a result of a sudden change in the nuclear shape, marking two regions of deformation. This feature provides a powerfull tool to assign experimentally quantum numbers and deformations in proton emitters.
