2012Go19: 216Pb was produced at GSI using a 1-AGeV 238U beam incident on a 2.5-g/cm2 9Be target. Fragmentation products were identified using the FRS fragment separator according to magnetic-rigidity, time-of-flight, and energy-loss measurements. Measured Eγ, isomer half-life.
2016Ca25, 2017Ca12: 216Pb was produced at GSI using a 1-GeV/u 238U beam incident on a 1.6-g/cm2 9Be target. Fragmentation products were identified by the FRS fragment separator according to energy-loss, time-of-flight, and magnetic-rigidity measurements. Measured T1/2.
2010Al24, 2009Al32: 216Pb produced by fragmentation of a 238U beam on a 2.5 g/cm2 Be target at GSI. Measured cross section.
