Attached is the particle-gated gamma-ray spectrum for run 5 (green), run 6 (blue), run7 (red).
In run 5 we see clearly transition of 2+1 --> 0+1 in 62Ni, while in run 6 both transitions are visible from 58Ni and 62Ni (which is a result
of a wrong beam tunning in to increase the intensity during which the ion changed by mistake). Now we are running with 58Ni (run 7) and waiting for |
