“…The reaction was very clean and the majority of observed lines belong to the decay of 74 Br to 74 Se. Contaminants observed in the spectrum were the decays of 73m Se and 71 As, however, their contribution was small and prior knowledge of their decay schemes [23,24] allowed for positive identification of their associated γ rays in the γ-γ coincidence matrix. The quality of the coincidence data is illustrated in Fig.…”

Probing collectivity in Zn isotopes with one particle or hole outside theN=40subshell closure

“…Partial level scheme of 7lZn showing the identified y-ray transitions observed in the present study according to the known 71 Zn level scheme[26].…”

“…4) created with a condition of y rays emitted at angles >135c it was possible to identify the following transitions: (3/2)" -* 1 /2 " a t674.3(8)keV, 5 /2 " ->• 1/2" a t468.4(8) keV, l / 2 " ,3 /2 " X 1/2" at 490.4(5) keV, (5/23)+ -> (3/2)" at 584.9(15) keV, and (3/2+.5 /2 +) -> (5/23)+ at 594.5(4) keV. The correspond ing level scheme, extracted from the known level scheme of 7lZn [26], is presented in Fig. 5.…”

New Millisecond Isomer Lifetime Measurements at LANSCE

“…The accepted value for the half life of this isomer is 20.40(17) ms [8], obtained by taking a weighted average of most of the previous dozen or so reported measurements. Our new result is lower than with this value, and due to the large signal-to-background ratio, is not very sensitive to assumptions about the background in our data.…”
