1998Do08,1994Be24: 208Pb(238U,F) with E(238U)=750 MeV/nucleon. Fission products separated using the FRS fragment mass separator and identified through energy loss and time of flight measurement. Identification of 136Sn isotopes.
2011Ar18,2002Sh08,2001Sh12: 238U(p,F) with E(p)=1 GeV. 136Sn selected with the Resonance Ionization Laser Ion Source (RILIS) followed by a high-resolution mass spectrometer. Measured β-delayed neutrons and βn(t) using the Mainz neutron long counter consisting of a three-ring concentric array of 50 3He proportional counters.
