【 摘 要 】

Proton emission from odd-odd nuclei is studied within the two quasiparticle plus rotor model which includes the non-adiabatic effects and the residual interaction between valence proton and neutron. Justification of the formalism is discussed through corroboration of our results with the experimental spectrum of180Ta. Exact calculations are performed to get the proton emission halflives. Our results for the proton emitter130Eu leads to the assignment of spin and parity Jπ= 1+ for the ground state. The role of Coriolis and residual neutron-proton interactions on the proton emission halflives and their interplay are also discussed.
