Dear all, I want to understand the injection function of heavier nuclei.
In 5.5.1 of the manual, in normalization of the nucleon primary source function, the source abundance of heavier nuclei is X = Q_A/Q_1 = A*C_A/C_1 ..., C_A/C_1 = X*A^(gamma1)*Z^gamma Why there is one more A here ? If it is like this: q_A(p_A) dp_A = q_A(p_A) *dp_A/dEk_n *dEk_n, where Ek_n is the kinetic energy per nucleon, and dp_A/dEk_n = A/beta Then in flux I(Ek) = c/4pi *n *A, and at last both of A are cancelled actually.
And for the corresponding secondary particle, there is one more A is formula 13 for secondary positron. And for secondary electron and antiproton. Maybe A_j ? But in secondary nuclei, there is no A, for example formula 20. Because it is the integral in p_A space? Here I have a question. In some literature, people assumed hard sphere approximation, i.e. before and after spalltion, kinetic energy per nucleon is conserved. But here in 19 and 20, it seems that you don't use that assumption. Right? How large is the difference between both two?
Thank you very much for your reply!
