Abstract
In this chapter we apply the formalism developed in the first part of the book to fission. We discuss the choice of collective coordinate adapted to the fission problem. We then present a quantum localization technique to progressively identify the wave function of the nascent pre-fragments within the wave function of the parent nucleus, and provide a quantum-mechanical definition of scission. We conclude with a discussion of the calculation of fission-fragment properties, in particular their mass distributions and total kinetic and excitation energies.

Notes
- 1.
It may be possible to recover the missing masses by introducing many additional multipole constraints, thereby emulating the constraints on the pre-fragments.
