Absolute differential cross sections were measured for the reactions N/ sup 15/(p,p)N/sup 15/, N/sup 15/(p, alpha /sub o/) C/sup 12 (ground state) and N/ sup 15/(p, alpha /sub 1/)C/sup 12*/ (first excited state). Thin gas targets, enriched up to 98% in N/sup 15/, and a 6-mil CsI(Tl) crystal detector were used. Numerous angles were studied for bombarding energies between 1 Mev and 3.6 Mev. Spins and parities are discussed where resonances suggest the existence of excited states in O/sup 16/. At the 1210 kev resonance. the incident energy for which the alpha /sub o/ yield is maximum depends on the angle of observation. This is probably the result of interference and has bearing on the spin and parity assignment of this level. The anomaly at 1890 kev cannot be positively identified as due to resonance. (auth)
