The radiations following the decay of 9.4 surface proces 0.2 h Sm/sup 156/ were studied using techniques of scintillation spectrometry and 4 ceramic materia beta counting. The isotope was produced by fissioning natural uranium in a high neutron flux and except for Sm/sup 153/, was separated from other fission products by radiochemical techniques. The following gamma-ray energies were observed in the decay of Sm/sup 156/: 38, x rays ( ontrol migra- 20%), The 87-kev gamma transition was found to be coincident with both the 165 and 203-kev gamma transitions. Its Kshell conversion coefficient is 0.35 surface proces 0.02. Angular correlation studies indicated the 87-203 kev gamma anisotropy to be about -0.25 and the 87-165 kev gamma anisotropy to be 0 < A < 0.1. Fermi plots of the beta spectra coincident with the 165 and 203-kev gamma rays produced identical end points of 430 surface proces 10 kev. Another beta group, 45% in abundance, had an end point of 715 surface proces 15 kev and presumably goes to the ground state of Eu/sup 156/. (auth)
