Lecture 2
Nuclear Fission
Outline
This lecture describes nuclear fission, its mechanism and
energetics.
The simplest model of nuclear fission is the liquid drop
model developed by Bohr, Wheeler and Frenke

Lecture 4
Propagation of Neutrons in Matter
Collimated Beams
Consider a mono-energetic neutron beam
beam hitting perpendicularly the boundary
of a semi-infinite, homogeneous medium.
These neutrons, which

Introduction
In the previous lectures, all neutrons in a reactor were assumed
to have the same speed or energy.
But neutrons are created at a very high energy ~2
