3. DESCRIPTION OF PROBLEM OR FUNCTION

INTEGR calculates escape and transmission probabilities in one-dimensional, cylindrical geometry  and generates a library for subsequent FACEL calculations. The probabilities are tabulated as a function of two parameters:
a.  K = RI/R0, inner radius of an annulus divided by outer radius.
b.  A = SUM(R0-RI), optical thickness of an annulus.

4. METHOD OF SOLUTION

The probabilities are calculated partly analy- tically and partly numerically applying the Gauss point integration.
