pb,o{R' > R) is identically zero for b = 0, while for 5 = 1 it is given 

 by the simple and exact formula 



Pi,o{R' > R) = erfc (i?/\2) - exp {- R'). 



Although in many of the computed values in Table I the last digit 

 (the third significant figure) cannot be regarded as reliable, it is 

 thought that the tabulated values are accurate to about one per cent 

 or better, which of course is quite adequate for all practical purposes.
