E(level): From least-squares fit to Eγ.

Jπ(level): Tentative values based on π=+ and π=- sequences observed in (40Ca,p2nγ) (2005Ma55) and consistent with authors’ spherical shell-model calculations in (π 2p1/2,1g9/2) model space.

E(level): π=+ GS band.
T1/2(level): Weighted mean from 890γ(t) and 973γ(t) following 91Rh ε decay (2004De40). Measured using a macrocycle of a beam-on period followed by a beam-off period, with on/off times tailored to suit the expected half-life of the isotope of interest. α time-to-digital converter was started at the beginning of each macrocycle to provide the time of each triggered event relative to the start. Others: 1.7 s 2 (2001Ki13); also, 1994He28 note that the observation of 91Rh in their study implies a mean life in excess of the ≈150 ns flight time through the fragment separator.
