Resumen
A level scheme is proposed for 'Rb, which was obtained through the 'Zn(' O, np) reaction at +4 and 52 MeV, by measuring y-y coincidences and y-ray angular distributions. The isotopic identification was made by studying onand oA'-beam spectra at selected time intervals, and determining the intensities of the different decay products. The main part of the level scheme comprises a hI = 1 band which shows a staggering similar to that previously found in ' Br and 'Kr. In addition the level energies are very close to those in ' Br. It was not possible to establish in a conclusive manner whether the lowest state of the proposed level scheme corresponds to one or the other of the hitherto known 6 and 17.5 min isomers in "Rb, but the first possibility appears to be the more likely one.
