General Comments:

1993Ja03: 120Pd produced and identified in 238U(p,F),E=20 MeV followed by on-line mass separation at JYFL facility; measured half-life of 120Pd, and K| x ray

2006Mo07: 120Pd produced by fragmentation of 136Xe+50,51, E=121.8 MeV/nucleon on Be. Particle identification was performed. The products were passed to a mass spectrometer, position sensitive detector, stacked Si detectors and tof arrangement. β-delayed neutrons were detected within the neutron emission ratio observer. Implantation and decay events were time stamped and correlated. Deduced T1/2 and Pn

Mass measurement: 2011Ha48, 2008Su19, 2007Ha20, 2004Ge18

Q-value: S(n)=11034 3, S(2p)=27600 200 (syst), Q(β-n)=294 15 (2017Wa10)
