DECAY OF Y$sup 8$$sup 8$
The weak positon spectrum in the decay of 105-day Y/sup 88/ was measured in coincidence with the 1.86-Mev gamma ray and annihilation radiation. The spectrum has an end-point energy of 560 plus or minus 30 kev. The spectral shape is found to be characteristic of a unique first-forbidden transition ( DELTA J = 2, yes), thus confirming a 4/sup -/-spin assignment for the ground state of Y/sup 8/. A search was made for a possible 0+ excited level below the 1.86 Mev (2+) level in Sr/sup 88/, with negative results. An upper limit of 100 kev can be set on any possible E2 transition to such a state. (auth)
