The α-decay chains originating from the πs1/2 and πh11/2 states in 173Au have been investigated following
fusion-evaporation reactions. Four generations of α radioactivities have been correlated with 173Aum leading to a
measurement of the α decay of 161Tam. It has been found that the known α decay of 161Ta, which was previously
associated with the decay of the ground state, is in fact the decay of an isomeric state. This work also reports on
the first observation of prompt γ rays feeding the ground state of 173Au. This prompt γ radiation was used to
aid the study of the α-decay chain originating from the πs1/2 state in 173Au. Three generations of α decays have
been correlated with this state, leading to the observation of a previously unreported activity which is assigned
as the decay of 165Reg. This work also reports the excitation energy of an α-decaying isomer in 161Ta and the Qα
value of the decay of 161Tag.

Darby, I. G.; Page, R. D.; Joss, D. T.; Bianco, L.; Grahn, T.; Judson, D. S.; Simpson, J.; Eeckhaudt, S.; Greenlees, P. T.; Jones, P. M.; Julin, R.; Juutinen, S.; Ketelhut, S.; Leino, M.; Leppänen, A.-P.; Nyman, M.; Rahkila, P.; Sarén, J.; Scholey, C.; Steer, A. N.; Uusitalo, J.; Venhart, M.; Ertürk, S.; Gall, B.; Hadinia, B. (American Physical Society (APS), 2011)The decays of the πd3/2 ground states of 156Ta and 160Re have been studied in detail using the GREAT spectrometer. More than 7000 160Re nuclei were produced in reactions of 290- and 300-MeV 58Ni ions with an isotopically ... -
