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. temperature (t9=1.e+9 K) Z A 2.0 2.5 3.0 4.0 5.0 7.0 10.0 sc 50 1.07E-02 1.19E-02 1.29E-02 1.43E-02 1.53E-02 1.65E-02 1.75E-02 mn 58 1.29E-01
