Production and identification:
1994Be24, 1997Be70, 1998Do08: 122Te produced and identified in Pb(238U,F) reaction at 750 MeV/nucleon at GSI facility; measured yields for 121,122,123,124,125Pd
1997So07: 208Pb(238U,F),E=20 MeV/nucleon; measured fragment yield
2006Mo07: 122Pd produced by fragmentation of 136Xe+50,51 (E=121.8 MeV/nucleon) on Be target using A1900 fragment separator at NSCL-MSU facility. Particle identification was performed by energy loss and tof techniques. The secondary beam was implanted into β-decay arrangement consisting of Si(PIN) detectors and Si strip detectors (DSSD) and single-sided Si strip detectors (SSSD). β-delayed neutrons were detected. Implantation and decay events were time stamped and correlated. Measured T1/2 and %pn. Consult also 2006ToZW thesis
