Abstract
Measurements of the oxygen total neutron cross section from 3.5 to 4.4 Mev and the reaction cross section from 4.0 to 5.2 Mev are presented. In a study of the reaction the following quantities were measured: the 0° yield from 0.8 to 3.5 Mev, 29° and 146° yields between 2.0 and 3.5 Mev, and 47 angular distributions in the range from 1.0 to 3.5 Mev. Cross sections for the and the reactions are compared using the principle of detailed balancing. On the basis of the angular distributions spin assignments for 14 states of between excitation energies 7 and 9 Mev are discussed, and in some cases relative parity assignments are made. Reduced widths of the states of were derived from the results of the experiments on the reaction and the oxygen total neutron cross section.
