Approximations of Recombination Probabilities for S, T, and F-Precursors

In this place we will consider the case where both A and (Ol  

Problems- . Prove that 7 in Eq. (3-36). Thus, the P/ value can approximately be given by 

The total fraction of pairs (P//) with nuclear state TV that recombines, is given by 

It is noteworthy from Eq. (3-42) that enters in Pn with a positive sign. In Eq. (3-37), however, ATn enters in P/f with a negative sign.
