Better Approximate Solutions of the Time-Independent Schrodinger Equation

Better Approximate Solutions of the Time-Independent Schrodinger Equation 

In this section we will summarize some methods which are more appropriate for slow collisions. Before pursuing these, however, we will deal briefly in Section IV-C (1) with a method of general applicability to spherically symmetric potentids. We do this now because the later elaboration of the slow-collision methods in Sections IV-C (2) to IV-C (4) will show that these are generally feasible only when approximations are made to reduce them at least partially to the methodology of Section IV-C (1). Probably because of their relative complexity, these methods have unfortunately had little or no application to specific chemical reactions.
