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
