III-121 



Figure III-44 graphs the above expressions for the surface loss per 

 bounce. The experimental data points are taken from (Ref. III-27). Marsh 

 comments that although the scatter is considerable, it is not surprisingly so, 

 and that the over-all fit is good. As pointed out before, Marsh's original re- 

 sult apparently has several numerical errors . Using the corrected form, we 

 obtain somewhat higher theoretical estimates. These tend to provide a better 

 fit to the experimental values .
