For an exponential shock wave we have, as in equation (76): 
ex p (- bx) 
Pler) = ae 
(127) 
Using the expansion for b in equation (77), the definition a” 
= 2UX/3C°%, and setting , 1@ equation (126) becomes:

The integral on the right hand side of equation (128) can be 
transformed in a manner very similar to that employed in 
obtaining equation (89) from equation (78). We set u =‘ga® and 
define
