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
