Script for calculating sigma-v for DT (note reactivity is given in cm^3 s^-1):
bg=34.3827;
mrc2=1124656;
c1=1.17302 *10^(-9);
c2=1.51361*10^(-2);
c3=7.51886*10^(-2);
c4=4.60643*10^(-3);
c5=1.35*10^(-2);
c6=-1.0675*10^(-4);
c7=1.366*10^(-5);
theta=T/(1-T(c2+T(c4 +T c6))/(1+T(c3 + T(c5 + T c7))));
ksi=(bg^2/(4 theta))^(1/3);
sigmav[T_]=c1 theta Sqrt[ksi/(mrc2 T^3)]E^(-3 ksi);
Table of reactivities:
