The spectra of secondary neutrons and gamma rays produced by neutron interaction in thick samples (approximately 1 mean free path) of liquid nitrogen and liquid oxygen have been measured as a function of the incident neutron energy over the range 1 to 20 MeV. Data were taken for angles of 30$sup 0$, 55$sup 0$, 90$sup 0$, and 125$sup 0$. A linac (ORELA) was used as a neutron source with a 47-m flight path. Incident energy was determined by time-of-flight, while secondary spectra were determined by pulse-height unfolding techniques. The results of the measurements are presented in forms suitable for comparison to calculations based on the evaluated data files. (32 figures, 42 tables) (auth).

Numerical values of differential cross section for gamma rays produced by neutron interactions with zinc were measured for neutron energies between 0.9 and 6 MeV for sigma = 120 deg. The d sigma /d omega data were obtained using a 35 cm/sup 3/ Ge(Li) detector. The data consist of cross section values for 31 gamma rays having E/sub gamma / between 300 and =780 keV. Neutron energy intervals varied between a minimum of ~50 keV at E/sub n/, ~ 900 keV and a maximum of ~1.5 MeV for E/sub n/ ~ 5.8 MeV. (auth).
