General Comments:

2006Mo07: 121Pd produced and identified in 9Be(136Xe,X) reaction at E(136Xe)=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.

2007To23; 9Be(136Xe,X) E(136Xe)=120 MeV/nucleon; fragment separator; Si(PIN), Si strip and single-sided Si strip detectors ; measured 135 keV γ from a isomer; no information is given on half-life

1997So07; 208Pb(238U,X) E=20 MeV/nucleon; fragment separator, tof, position sensitive detector; measured yield; no information is given on decay properties.

1998Do08: 208Pb(238U,X) E=750 MeV/nucleon; fragment separator, tof; measured yield; no information is given on decay properties.

2004Ge18: 208Pb(238U,X) ,209Bi(238U,X); fragment separator, tof, Schottky mass separator; measured mass; no information is given on decay properties.
