Structure of the proton drip line nucleus $^{17}$F

Abstract

The odd $A$ proton drip line nucleus $^{17}$F has been studied in a semi-microscopic model which couples proton quasiparticle motion to the vibrational motion of the neighbouring even-even $^{18}$Ne core. The experimentally observed low lying excitation spectrum, electric quadrupole moment, magnetic dipole moment, $B(E1)$ and $B(E2)$ values have been fairly well reproducd. The calculated rms radius of the first excited state is well reproduced and is found to be larger than that of the ground state which agrees with the experimental observation.
