The odd a proton drip line nucleus 17F has been studied in a semi-microscopic model which
couples proton quasi particle motion to the vibrational motion of the neighbouring even-even
18Ne core. The experimentally observed low lying excitation spectrum, electric quadru pole
moment, magnetic dipole moment, B(E1) and B(E2) values have been fairly well reproduced.
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.
