Q(β-)=9.8×103 keV SYS(n)= 5.7×103 keV SYS(p)= 1.37×104 keV SYQ(α)= -1.05×104 keV SY
Reference: 2012WA38

General Comments:

2006Mo07: 121Rh produced and identified in 9Be(136Xe,X) reaction at E136Xe=121.8 MeV/nucleon. fragment separator, Si(PIN) detectors, Si strip detectors, single-sided Si strip detectors. Implantation and decay events were time stamped and correlated. Measured half-life from β spectrum.

Others (tentative evidence for the formation of 121Rh):

1998Do08: 208Pb(238U,X) E=750 MeV/nucleon. fragment recoil separator. measured (fragment)(β and/or γ) coincidence. Tentative evidence for the formation of 121Rh with a measured fractional yield of 0.005 3.

1994Be24 (from the same lab as 1998Do08): same reaction as in 1998Do08, 3 counts assigned to 121Rh

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

Q-value: ΔQ(β-)=1034, ΔS(n)=1082, ΔS(p)=1208, ΔQ(α)=1142 (2009AuZZ)

Q-value: Q(β-n)=4996 909 (syst,2009AuZZ)
