General Comments:

Other Reactions:

Br(γ,γ’): photoexcitation of 35-μs 536 level via intermediate structures at 3.45 MeV 15 (1990Po07) and at 4.80 MeV 15 (1993Du10).

2015Al19: Isotopic yield cross section σ(81Br)=0.125 mb 17, in spallation of 136Xe-induced reactions on deuterium at 500 MeV/nucleon.

Q-value: S(2n)=18051.6 14, S(2p)=18919 5 (2021Wa16)

E(level): For a least-squares fit to adopted Eγ, assigning ΔE=1 keV to Eγ data for which no uncertainty was reported by the authors. Eγ data from (d,nγ) are within 0.2 keV of those determined precisely in other reactions, whenever comparison can be made.

T1/2(level): From DSAM and/or Doppler broadening in Coulomb excitation (except as noted) for E(level)<6 MeV; Γ(tot) from 80Se(p,p), (p,n) IAR otherwise.
