Abstract
The confirmation of the 0+ spin assignment and the halflife value of the first excited state of 68Ni has been derived from the time spectra obtained in the coincidence measurement of the 160 from the 70Zn(14C, 16O)68Ni * reaction with the electrons associated to the decay of this level.
Résumé
La période du premier niveau (0+) du 68Ni a été déterminée à partir du spectre en temps obtenu dans la mesure des coincidences des 16O de la réaction 70Zn(14C, 16O) 68Ni* et des électrons, associés à la décroissance de ce niveau. L'attribution du spin 0+ a été ainsi confirmée.
