The calculations are mainly concerned with the flux distribution ψ(r, u, t) and the spatially dependent most probable slowing down time tmax(r, u). The analytic solution for ψ(r, u, t) indicates that its spatial dependence is determined only by the time-dependent neutron age τ(u, t), while tmax(r, u) is shown to be dominantly influenced by the stationary neutron age τs(u).Through these analyses, the interesting relations are obtained: (a) When <math><mtext>t = t</mtext><msub><mi></mi><mn>s</mn></msub><mtext> ≡ «t</mtext><mtext>a</mtext><mtext>̊</mtext><msub><mi></mi><mn>0</mn></msub><mtext>{1 − ξ/(ξ + 4)(ξ + 2)}</mtext></math>, τ(u, t), coincides with τs,(u), which implies that the spatial dependence of ψ(r, u, t) at that time is analogous to that of the stationary neutron distribution, where «tå0 is the first time moment.

A comparison is made with the slowing down spectrum calculated from 241Am-9Be source. The effects of using different models for inelastic scattering by oxygen atom in water molecule on the slowing down spectrum are also investigated.
