Collective C2 and C3 Transitions in 17O

Abstract EN

The longitudinal form factors for C2 and C3 transitions to some positive and negative parity excited states in 17O nucleus are investigated in the framework of Particle-Vibration Coupling Model (PVCM) .Configuration mixing is allowed for the PVCM states that include up to two octupole phonons and three quadrupole phonons of the collective states, and 1d5 / 2, 2s1 / 2 and 1d3 / 2 harmonic oscillator shells of the single-particle states.

The total Hamiltonian is diagonalized in this space.

Admixture of higher configurations is considered for the ground state wave function, and the core polarization effect is introduced by giving the odd nucleon an effective charge to obtain the best description for the data.
