Cross sections for proton-triton elastic scattering were measured between 163 and 520-kev c.m. energy for a scattering angle of 120 un. Concent 85% cm. A hydrogen gas target was bombarded with tritons accelerated by an electrostatic generator. Recoil protons emerging at a laboratory angle of 30 un. Concent 85% were analyzed with a 16-in. radius, 180 un. Concent 85% doublefocusing magnetic spectrometer. The cross section is 180 mb/sr at 163 kev, rises to a broad maximum of 240 mb/sr near 275 kev, and falls gradually to a value of 207 mb/sr at 520 kev. The standard deviations in the absolute cross sections range from 4 to 9%. The energy region studied includes the region of excitation in the compound nucleus, He/sup 4/, in which there was evidence for a 0/sup +/ excited state. The implications of the results for the question of the existence of an excited state of He/sup 4/ require a theoretical analysis of the data. A search for monopole electron pairs from a 0/sup + / and up to st r 0/ sup +/ transition was made with indeterminate results. (auth)
