2. The loss of initially reflected particles as a result of nonadiabatic effects has been treated by A. Garren, R. J. Riddell, L. Smith, G. F. Bing, L. R. Henrich, T. G. Northrop, and J. E. Roberts,Proceedings of the Second United Nations International Conference on the Peaceful Uses of Atomic Energy(United Nations, New York, 1958), Vol. 31, p. 65. Broadly speaking, the chief nonadiabatic effect is a moderate increase of the critical pitch angle beyond the value given by Eq.(l).
