Precision mass measurements utilizing beta endpoints

A technique for precise determination of beta endpoints with an intrinsic germanium detector has been developed. The energy calibration is derived from gamma -ray photopeak measurements. This analysis procedure has been checked with a /sup 27/Si source produced in a (p, n) reaction on a /sup 27/Al t...

Sumario:A technique for precise determination of beta endpoints with an intrinsic germanium detector has been developed. The energy calibration is derived from gamma -ray photopeak measurements. This analysis procedure has been checked with a /sup 27/Si source produced in a (p, n) reaction on a /sup 27/Al target and subsequently applied to mass separated samples of /sup 76/Rb, /sup 77/Rb and /sup 78/Rb. Results indicate errors <50 keV are obtainable. (29 refs).
