General Comments:

2004Ke06: 176Tl identified in 102Pd(78Kr,p3n) E=380-405 MeV reaction at JYFL using RITU gas-filled recoil separator. The isotopic identification was achieved by position, time and energy correlations between implanted nuclei and α-decays of the daughter nuclide 175Hg (Er-proton-α’s from mother and daughter correlations). Measured proton energy, half-life, and search for α decay of 176Tl

2007Me28: calculated proton decay half-life=0.13 ms for L=0 transition

Q-value: Note: Current evaluation has used the following Q record

Q-value: S(n) from 1997Mo25, S(p) from measured E(p)(lab)=1258 18 (2004Ke06), Q(α) from systematics (2003Au03, 2009AuZZ) with uncertainty=250 keV.

Q-value: S(p)=-1250 220, Q(εp)=10700 200, s(2p)=-170 220 (syst,2003Au03,2009AuZZ)

2004Ke06 searched for α decay, but none was observed, thus proton decay mode is assigned ≈100%. Calculated half-lives (1997Mo25): 1.2 ms for α decay and 362 ms for β decay. This suggests that α decay mode should compete favorably.
