Abstract
This chapter focuses on the properties of the fission fragments. A brief overview of some of the experimental techniques used to study fission is given, and the properties of fission-fragment detectors are presented. The double-energy technique, used to extract fission-fragment properties, is examined in some detail. The functional forms commonly used to model the distribution of the fission fragments as function of both their mass and their charge numbers are discussed. The origin and distribution of excitation energy and angular momentum in the fragments are also discussed and related to experimentally observed quantities. The independent yields of the fission fragments, taken to be the yields of the fragments prior to beta decay, and the cumulative yields after beta decay are discussed. The activities of the beta decaying species can be understood using the Bateman equations, and the chapter concludes with an extensive discussion of the solution of these equations and how they are used to calculate both independent and cumulative yields.
