Q(β-)=6573 keV 20S(n)= 7.20×103 keV 4S(p)= 11930 keV 22Q(α)= -9.78×103 keV 4
Reference: 2012WA38

References:
  A  127Cd β- decay  B  127In IT decay (9 μs)

General Comments:

Nuclear structure calculations on the levels and their properties: (2004Po10), (1992Ar26), (1986Ar09)

Levels: 2000Pi03 suggested an existence of possible high-spin isomer in 127In which decays to 19/2+ state in 127Sn. This isomer can be attributed to the 1863 keV (21/2-) state proposed by 2004Ga24.

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

Q-value: Δ(Q(α))=210 (2003Au03)

Q-value: Measured Q(β-) from 1.09 s state in 127In to ground state in 127Sn by β-γ coincidence method is 6579 keV 20 (2004Ga24) and 6514 31 (1987Sp09).

Q-value: Measured Q(β-) for 3.67 s state in 127In to ground state in 127Sn by β-γ coincidence method is 6999 keV 63 (2004Ga24).

Q-value: Measured Q(β-) from 1.04 s state in 127In to ground state in 127Sn by β-γ coincidence method is 8442 keV 56 (2004Ga24).
