Radiochemistry Fuel Cycle Summer School 2015


This lecture discusses alpha decay in radionuclides.  Theories on alpha decay are presented. Systematics and energetics involved in alpha decay are presented.  The correlation between Q value and decay energy is described.  The Geiger Nuttall relationship is provided, described, and utilized in a model for alpha decay. Tunneling is also exploited to described alpha decay, coupling energy and half-life.  Gamow calculations are shown to reflect the Geiger Nuttall relationship. Hindered alpha decay is discussed. Hindered alpha decay is employed to described nuclear properties. Hinderance factors are described, along with how they are calculated and where they can be found. Proton and other charged particle emission are presented. The lecture is 37 minutes in length.
