The weak positron spectrum in the decay of Y/sup 88/ has been investigated using a 4 pi -positron-scintillation spectrometer. Two measurements of the spectrum yield experimental shape factors which are consistent above 250 kev with that expected for a unique once-forbidden transition. The average end- point energy obtained in these two measurements is 761 plus or minus 9 kev. The positron branching was measured and found to be 0.20 plus or minus 0.01%. The log ft is 9.4, and log f/sub 1/t is 8.7. On the basis of recent measurements of the gammaray intensities in the Y/sup 88/ decay the electron capture branching to the 1840-kev level is determined to be 5.8 plus or minus 0.7%, which yields an electron capture to positron ratio of 29 plus or minus 4 for this transition.
