1. Mathematically speaking, what do temperature distribution
in a rectangular plate (Figure VIIb.2.1) and neutron flux distribution in a
cylindrical core have in common?

2. Why, in an elastic scattering between a fast neutron and
a nucleus, is most energy lost in collision with light nuclei than with heavier
nuclei?
