Résumé
During test runs dedicated to the commissioning of ALTO (Accélérateur Linéaire et Tandem à Orsay), β and β-n decay of the very neutron rich could be observed at the tape station installed on-line with the PARRNe mass-separator. γ-lines observed in the resulting spectra and a careful analysis of the balance of their relative intensities point toward the existence of two β-decaying states in 84Ga. The decay of these long-lived states appear to feed the and excited states of and the state in allowing a significant improvement of the knowledge on nuclear structure in the immediate vicinity of 78Ni.
