“…It was also shown that in addition to the full energy peak there exists a low energy tail due to backscattering and a high energy tail due to annihilation radiation. Wohn et al [20] If the decay scheme is not known sufficiently well, or if the source strength does not allow coincidence measurements, only a lower limit can be given for the Q-value.…”

Abstract. Total decay energies have been measured for a number of neutron-deficient Rb and Cs isotopes, as well as for some neutron-rich isotopes of Fr and Ra. Mass separated sources were produced at the ISOLDE on-line separator at CERN. By applying two different /3-7 coincidence methods, Q values or their lower limits were determined for 76 78Rb ' 80Rb ' 121-124Cs ' 222Fr ' z24-Z26Fr ' 229Ra 229Ac" For many of these nuclei, the atomic mass excesses could be derived, allowing the comparison of masses of far unstable nuclei with predictions from mass formulae. The odd-odd nuclei 76Rb and 78Rb appear to be 1-1 89 MeV more strongly bound than expected from the systematics.
