Abstract: | Summary The linear integral transport operator for slab geometry is formulated and studied as a mapping on the set of measures on
the phase space of the underlying system, with the expected number of neutrons emergent from a collision represented by a
measure on the space of outgoing velocities. Under appropriate assumptions it is shown that, if c represents the maximum number
of secondary particles per collision, then there exists c
1
≥1 such that the system is subcritical for c≤c
1
. An example shows that c
1
≥1 is sharp in general, but further assumptions are given under which one can deduce c
1
>1. The idealized laws of elastic and inelastic scattering are shown to satisfy our assumptions.
