Characterizing the atomic mass surface beyond the proton drip line via α-decay measurements of the πs_1/2 ground state of ¹⁶⁵Re and the πh_11/2 isomer in ¹⁶¹Ta

RADIOACTIVITY ¹⁷³Au, ¹⁶⁹Ir, ¹⁶⁵Re, ¹⁶¹Ta(α)[from ⁹²Mo(⁸⁴Sr, X), E=392 MeV]; measured Eα, Eγ, Iγ, (recoils)α-, γγ-coin, αγ-delayed coin, branching ratio, half-lives using RITU separator, EUROGAM Phase-1 type Ge detectors, GREAT spectrometer at Jyvaskyla; deduced h_11/2 isomers, reduced widths, δ², hindrance factors, Q(α).

NUCLEAR REACTIONS ⁹²Mo(⁸⁴Sr, X)¹⁷³Au, E=392, 400 MeV; measured Eγ, Iγ, αγ-, γγ-coin; deduced prompt γ. No level scheme deduced for ¹⁷³Au.

ATOMIC MASSES ¹⁴⁹Ho, ¹⁵³Tm, ¹⁵⁷Lu, ¹⁶¹Ta, ¹⁶⁵Re, ¹⁶⁹Ir; deduced mass excesses and compared with AME-2012 evaluation.
