temperature dependent beta decay rates (b-) in units of inverse seconds both the ground and isomeric state are assumed to be in thermal equilibrium the rate is given in Clayton (1968) rate = (jg*rg+ji*ri*exp(-11.605*ei/t9)) 1 /(jg+ji*exp(-11.605*ei/t9))) where jg = 2J_0+1 for the ground state rg = decay rate for the ground state ji = 2J_i+1 for the isomeric state ri = decay rate for the isomeric state ei = energy (in MeV) of the isomeric state above the ground state t9 = temerpature in units of 1.e+9 kelvins For beta decay, we list for each (Z,A) the decay rate OUT OF the isotope. The isotope listed is the PARENT of the beta decay. example: the value 6.76E-03 (line 1, column 3) gives the decay rate for sc50 -> ti50 at temperature t9 = 0.03 temperature (t9=1.e+9 K) Z A 0.03 0.05
