Reference: 2017WA10

References:
  A  140Sb β- decay 

General Comments:

Produced by Pb(238U,F), E=750 AMeV (1994Be24, 1998Do08), production cross section σ=78 μb (1994Be24). Identification by time-of-flight.

2006KeZZ: 238U beam of 750 MeV/u on Pb target, fragments following projectile fission separated, identified, and implanted into four double-sided silicon strip detectors; measured T1/2.

2004Sh46 calculated B(E2)|^ for g.s., and energy and g factor for 2+1 state (no numerical values given).

2017Mo12: most extensive data and study of 140Te from 140Sb β- decay (see dataset).

Proposed level scheme is from 2017Mo12

Q-value: Uncertainties based on syst are: ΔQ(β-)=600, ΔS(p)=410, ΔQ(α)=310

Q-value: Q(β-n)=3820 60 (2017Wa10)
