;
The electron capture decay of Sn/sup 1//sup 1//sup 3/ was investigated using scintillation detectors and coincidence circuitry. Decay was found to occur to the 650 snd 393 kev states of In/sup 1//sup 1//sup 3/ with branching ratios of (1.8 plus or minus 0.1)% snd (98.2 plus or minus 0.1)%, respectively. The 650 kev state decayed by the emission of a 255 kev gamma ray to the 393 kev state. No evidence was found for the existence of a proposed 648 kev crossover transition. An upper limit for the intensity of this transition was placed as 0.1% of that of the 255 kev transition. The orbitai electron capture ratio to the 648 kev state was determined to be (P/sub L//sub M//sub N// sub .//sub .//sub ./ /Pi minimum decay energy to the 648 kev state was assigned as 150 kev. It was determined that trsnsitions to the 393 kev state of In/sup 1//sup 3/) were first forbidden by considering log ft values; this was consistent with a spin and parity of 1/2+ or 3/2+ for the ground state of Sn/sup 1//sup 1//sup 3/. The 648 kev state was assigned a spin and parity of 1/2- or3/2- on the basis of possible log ft values for the absence of the 648 kev crossover transition. (auth)
