Abstract
The most proton-rich particle-stable or quasi-stable copper isotope identified in projectile fragmentation reactions is 55Cu. 54Cu was found unbound a few years ago in such an experiment. The present note reports on a reanalysis of data to determine a life-time limit for 53Cu. A comparison with data for 52Ni and 54Zn combined with EPAX calculations allows to determine a life-time limit of this nucleus of 130ns which, in a simple barrier penetration model, yields a one-proton separation energy of −350 keV. This experimental limit is in agreement with a prediction from the latest Atomic Mass Evaluation and with other model predictions.
