Abstract :
Escape and transmission probabilities, defined in terms of both the
region the neutron originates from and the region it penetrates, are used to
develop new interface--current relations for unit-cells with an arbitrary number
of annular regions in cylindrical and spherical geometries. Comparisons with
currents, obtained in terms of standard transmission and escape probabilities,
as well as with accurate results reported in the literature, are presented for
selected situations, showing significant discrepancies between the two models.
