SAMPLE A beryllium oxide target with thickness about 294 - M057500100013
512 mg/cm**2 increased as the photon energy was M057500100014
raised. M057500100015
DETECTOR (MWDC) M057500100016
ANALYSIS Cross sections were extracted from the experimental M057500100017
photoproton energy spectra by fitting four component M057500100018
for the final nucleus ground and three excited states M057500100019
plus a uniform background. The shape of each M057500100020
component in the computed proton end-point spectrum M057500100021
was determined mainly by that of the incident photon M057500100022
spectrum, but the additional contributions from the M057500100023
proton energy loss in target, the electron-beam M057500100024
energy resolution, and the spectrometer resolution M057500100025
were folded in. M057500100026
ERR-ANALYS (ERR-S) Statistical errors. M057500100027
(ERR-SYS) The systematic errors M057500100028
were estimated (in quadrature) to be 7.4 % from the M057500100029
following sources: M057500100030
(ERR-1) solid angle 0.5% M057500100031
(ERR-2) beam-current integration 1.0% M057500100032
(ERR-3) real-photon spectrum 5.0% M057500100033
(ERR-4) virtual-photon spectrum 4.0% M057500100034
(ERR-5) electron-beam and spectrometer calibration 1.% M057500100035
(ERR-6) spectrometer dispersion 0.7% M057500100036
(ERR-7) dead-time corrections 1.0% M057500100037
(ERR-8) target thickness 1.0% M057500100038
(ERR-9) radiator thickness 0.3% M057500100039
(ERR-10) nuclear interactions in detectors 3.0% M057500100040
COMMENT The photoproton knockout reaction on 16O leaving 15N M057500100041
in low-lying bound states has been observed over the M057500100042
photon energy range from 196 to 361 MeV. The angular M057500100043
distributions for the reaction populating the ground M057500100044
state of 15N develops sharp structure as photon M057500100045
energy is increased but that for population of the M057500100046
excited states is smooth. The results are not M057500100047
explained by existing theoretical models. M057500100048
