A discussion of some one-dimensional fission processes with particular attention to questions of critical length and energy dependence of the products of fission. Various interconnections between the functions used in the invariant-imbedding approach and the classical approach are indicated. In addition, it is shown how one may pass from the consideration of certain linear two-point boundary-value problems to nonlinear (Riccation type) initial-value problems. The former are useful for theoretical considerations, the latter for numerical computations. 30 pp.
