Abstract:
16F is an exotic nucleus near the proton drip line. All states of
16F are unstable and can decay by proton emission. Up to now, the spin-parity values and excitation energy of the four low-lying states in
16F have been determined by experiment. However, discrepancies still exist among proton widths. The
15N(d, p)
16N angular distributions were measured precisely. The neutron spectroscopic factors of
16N ground state and first three excited states were determined. The proton widths of the four low-lying states of
16F were deduced to be （29.9±4.1） keV, （108±13） keV, （5.04±0.48） keV and （14.5±1.4） keV, respectively, according to the charge symmetry of mirror nuclei. The present results provide important crosscheck for the proton widths of
16F experimentally.
