Q(β-)=-4500 keV SYS(n)= 6710 keV SYS(p)= 790 keV SYQ(α)= 10670 keV SY
Reference: 2017WA10

  A  272Rg α decay (3.8 MS) 

General Comments:

268Mt produced as α-daughter of 272Rg, the latter produced in the bombardment of 243Am target with 48Ca beam.

See 272Rg Adopted Levels for production and half-life at three laboratories: GSI (1995Ho04,2002Ho11); Berkeley (2004Fo08) and RIKEN (2004Mo26)
