An experimental investigation has been made of the
cross section for the N14(pγ)O15 reaction using protons
accelerated by an electrostatic generator. Excitation
curves have been obtained from Be3N2 targets, nitrogen gas
targets, and a thin target formed by proton bombardment of
a copper foil in a nitrogen atmosphere. It has been found
possible to describe the experimental cross section from
.250 to 2.6 MeV by assuming the existence of nine resonances.
The parameters appropriate for a theoretical description of
the resonances are determined from the experimental data.
The yields from the various resonances are extrapolated to
the low energies corresponding to stellar temperatures. It
has not been possible to make more than very uncertain assignment
of such properties as the angular momentum and
parity for the excited levels in O15 that are indicated by the
cross section.
