The weak positon spectrum in the decay of 105-day Y88 has been measured in coincidence with the 1.86-MeV gamma ray and annihilation radiation. The spectrum has an end-point energy of 560±30 keV. The spectral shape is found to be characteristic of a unique first-forbidden transition (ΔJ=2, yes), thus confirming a 4--spin assignment for the ground state of Y88. A search was made for a possible 0+ excited level below the 1.86 MeV (2+) level in Sr88 with negative results. An upper limit of 100 keV can be set on any possible E2 transition to such a state.
