- Summary
- About four-fifths of the energy of the fission process is shared by the two heavy fragments into which the nucleus splits. This energy, of about 80 Mev. per fragment, is transferred to the medium in which the fission takes place in two ways. First, because each fragment is stripped of about half of its electrons during most of its path, it will interact strongly with electrons and thus lose energy through ionizing collisions with other atoms. Secondly, the fragments will lose energy by elastic collisions with atoms as a whole. Each fragment leaves in its wake a cloud of moving electrons and atoms. This cloud will roughly resemble a cylinder whose radius will increase with time on account of the motion of the struck electrons and atoms. They may now investigate two features of the slowing down process. First as it affects the fragment, i.e. we calculate its range, straggling, etc. And secondly they may work out the motion of the cylinder of moving particles, its effect on the medium, etc.
