A new isotpe 163Gd
- 1. Idaho National Engineering Lab., Idaho Falls (USA)
Description
A new isotope, 163Gd, has been identified which was produced in the spontaneous fission of 252Cf. The half-life of this isotope was measured to be (68 +- 3) s and eleven γ rays have been assigned to its decay. The assignment of this activity to 163Gd is based on the presence of these γ rays in the gadolinium fraction, which was chemically separated from mixed fission products, and on the observation of the growth and decay curve associated with γ rays from 19.5-min 163Tb, the daughter activity. Two new γ rays have been identified by half-life as belonging to the decay of 162Gd. Gamma-ray energies and intensities are reported for the 162Gd and 163Gd isotopes. (orig.)
