From Wikipedia, the free encyclopedia

• 70Zn is stable, 5e+14 a is the lower limit on its half life (to ββ decay).
• 76Ge is radioactive (two-neutrino double beta decay) with T1/2=1,5(1)×10²¹ yr.
• 78Kr is stable, 2.0e+21 a is the lower limit on its half life (to ββ decay).
• 116Cd is radioactive (two-neutrino double beta decay) with T1/2=3,0(2)×10¹⁹ yr. --V1adis1av (talk) 23:27, 28 February 2008 (UTC)
