ELASTIC SCATTERING AND REACTIONS OF PROTONS ON ARGON-40

Technical Report ·
OSTI ID:4056658
Thin targets of natural argon gas were bombarded with protons with energies between 0.8 and 3.5 Mev. Differential cross sections were measured at three angles for elastic scattering and for the reactions Ar/sup 40/(p,p gamma ) and Ar/sup 40/(p, alpha ). Many anomalies were observed in the elastic scattering cross section, the strongest being at 1.88, 2.45, and 3.4 Mev. j pi =3/2- and 1/ 2+ were assigned to the levels corresponding to the first two strong anomalies. The anomalies s/sup 0/(p, gamma ) resonances were too small to be detected. In the range of incident proton energy between 2.4 and 3.4 Mev, there were about 40 resolved or partly resolved resonances in the alpha particle yield. (auth)
