Abstract

The new nuclide /sub 37//sup 74/Rb has been observed at the ISOLDE-2 facility using a novel metal powder target operated at 2200 degrees C, and a Delta E-E beta telescope. Calculations support the conclusion that the observed half-life of 59+or-2 msec is superallowed beta decay from a T=1, I=0/sup +/ ground state in this heaviest Z=N nuclide known. (12 refs)
