#### Abstract

The spectral function of the $\sp{16}$O(e,e$\sp\prime$p)$\sp{15}$N reaction has been measured in quasielastic parallel kinematics. Momentum distributions are extracted for several discrete states, with special emphasis on the low-lying positive parity states of $\sp{15}$N. Spectroscopic factors and bound state wave functions are deduced from a distorted wave impulse approximation analysis, including coupled channels effects, employing five different optical potentials. The distribution of spectroscopic strength is determined out to E$\sb{m}$ = 40 MeV from a multipole decomposition of the spectral function continuum. The spectroscopic factor of the 2$s$1$d$ shell of $\sp{16}$O, as evidenced by transitions to the positive parity (2s$\sb{1/2}$,1d$\sb{5/2}$) doublet at E$\sb{x}$ = 5.3 MeV, is found to be 0.269 $\pm$ 0.018. The summed spectroscopic strength of the valence 1$p$ shell exhausts only 72% $\pm$ 5.5% of the independent particle shell model limit.
