| Abstract | ||
| The structure of 70Ni nucleus is studied by using Particle-Vibration Coupling Model (PVCM), which separates the nucleus into three systems, vibrating core and two interacting neutrons. The vibration of the core is represented by single quadrupole phonon, and the two neutrons are assumed to occupy the state 1g9/2 and interacted by MSDI. A very well reproduction for the positive parity states of 70Ni is obtained by applying the PVCM. The core polarization effect that includes particle-hole excitation from the proton states of the core, to the states outside the model space with 2ℏω, is very necessary to reproduce the reduced E2 transition probability. | ||
