CHEM 418 Nuclear Chemistry, Winter 2019: Lecture 5 Beta Decay

Beta decay is presented in this lecture. The neutrino hypothesis and its relationship with beta decay is discussed. A review of Q value calculations for beta decay is provided.  The importance of spin and parity, and how it can be used to assess beta decay, is discussed. Modeling beta decay through the weak force is provided. The impact of Coulomb interactions on positron and electron spectral shape is presented.  The use of Kurie plots in understanding beta decay is introduced.  Selection rules in beta decay and beta transitions are explained. Calculating logft and its relation to spin and parity are presented. Double beta decay is discussed. The lecture time is 48 minutes.

The lecture is assigned on Tuesday 22 January 2019 and due Sunday 27 January 2019.  When you have completed the lecture please comment on the blog and respond to the Lecture 5 PDF quiz.  The answers to the Lecture 5 PDF quiz will be posted Monday 28 January 2019.
