23.W. B. Maier II and E. Murad, J. Chem.

Murad’s cross section for is a factor of 1.7 smaller than Maier’s; thus, the present cross sections may perhaps be roughly a factor of two higher than the true cross sections.

27.If product ions are scattered isotropically in the laboratory, then from geometrical considerations, one expects (The value of 13 given in Ref. 16 is incorrect.) Perhaps the are scattered peculiarly, but it is also possible that very small stray fields may be present in the reaction chamber. Although such stray fields could seriously perturb the collection of very slowly moving secondary ions, there is no other evidence to suggest that significant fields are present.

34.Several sets of U and ε were tried, and the sets which seemed to provide the best representations of the data were chosen. A more formal mathematical procedure, such as a least‐squares fit, was not attempted.
35.This theory has, however, been applied to several reactions like reaction (1). See Refs. 5, 9, and 10.

37.The expression actually used for w is taken from Refs. 1 and 12, and it appears to differ from Eq. (105) on p. 667 of Ref. 9 by a factor of 4; however, the definitions of in Ref. 9 and of in Ref. 12 account for this difference.
