Q(β-)=-6.7×103 keV SYS(n)= 1.03×104 keV SYS(p)= 1.1×103 keV SYQ(α)= 1.4×103 keV SY
Reference: 2012WA38

General Comments:

β-delayed proton precursor.

Assignment: 92Mo(36Ar,αpn) E(36Ar)=205 MeV, on-line ms and 122La(β+p); Ba K| x ray observation (1984Ni03)

1984Ni03 measured (p)(K| x ray)-coin, E(p)=2.0-4.6 MeV; T1/2(122La)=8.7 s 7, proton-branching ratio was not given (1984Ni03)

Other: 1988WiZN: 92Mo(36Ar,3p3n) E(36Ar)=188 MeV, dual telescope counters; measured (p)(K| x ray)-coin

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

Q-value: ΔQβ=500 keV, ΔS(n)=590 keV, ΔS(p)=330 keV,ΔQ(α)=300 keV from atomic mass systematics (2003Au03)
