Measurements of the oxygen total neutron cross section from 3.5 to 4.4 Mev and the O/sup 16/(n, alpha )C/sup 13/ reaction cross section from 4.0 to 5.2 Mev are presented. In a study of the C/sup 13/( alpha ,n)O/sup 16/ 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.O to 3.5 Mev. Cross sections for the O/sup 16/(n, alpha )C/aup 13/( alpha ,n))/sup 16 /reactions are compared using the principle of detailed balancing. On the basis of the C/sup 13/( alpha ,n) angular distrfbutions spin assignments for 14 states of O/sup 17/between excitation energies 7 and 9 Mev are discussed, and in some cases relative parity assignments are made. Reduced widths of the states of O/sup 17/ were derived from.the results of the experiments on the C/sup 13/( alpha ,n) reaction and the oxygen total neutron cross section. (auth)
