Title: Importance of Coriolis interaction and pseudo-spin doublets in deformed proton emitters

Abstract

Theoretical aspects in the calculation of the half lives for proton decay from deformed nuclei lying beyond the proton drip line are discussed. The presence of pseudo-spin doublets close to the Fermi energy depends strongly on the parameterization of the single particle mean field. The calculation of the decay widths from these states, is very sensitive to the Coriolis coupling, and the pairing residual interaction cannot be ignored in these studies, for a correct interpretation of data.
