Microscopic rotation particle coupling for triaxial proton emitters

Study of triaxially deformed proton emitters provides us with rich information about the nuclear structure and decay properties at the extreme of the nuclear landscape, where many phenomenological assumptions may fail. The theoretical study of these nuclei can give us an opportunity to find some interesting features and phenomenon related to the nuclei beyond the drip lines, where the experimental data are scarce. The simpler implementation of the rotation particle coupling is termed as the particle rotor model (PRM) where the rotor is assumed to be rigid. Often, a variable moment of inertia (VMI) is considered in order to take into account the nonrigid behavior of the core. In the microscopic rotation particle coupling the experimental core energies are utilized to obtain the matrix elements of the particle-plus-rotor (PR) system. This idea is based on coupled channel calculations for axially symmetric nuclei given
