Fall 2016: RDCH 702 Lecture 6 Decay Kinetics

This lecture covers the fundamental equations that describe the decay of radionuclides; covered in two parts. Basic equations and their utility are presented. The implications on error from counting is provided.  Equations for mixtures, equilibrium, and branching of radionuclides are covered.  The use of a program to solve the Bateman equation is presented. The use of cross sections in determining production rates are covered. Saturation in isotope production due to the decay of the daughter is described. Discussion of natural radiation and dating are given. Examples are provided using the equations under a host of conditions. These include examples for dating from ²³⁸U, ¹⁴C, and the Oklo reactor. Lecture 1 is 44 minutes, lecture 2 is 31 minutes.  The PDF quiz is due 24 October 2016.

Fall 2016: RDCH 702 Lecture 5 Nuclear Models

This lecture provides supplemental information on the shell model and nuclear force. The strong force is introduced through isospin. A comparison of exchange particles is provided. The use of mirror nuclei to examine the strong force is presented. An overview of nuclear potentials is provided and used to discuss the shell model. States of the shell model and their relationship to magic numbers are discussed. Use of the shell model is determine nuclide spin and parity is presented. The relationship between spin and parity with nuclear deformation is introduced with Nilsson diagrams. Additional information on Nilsson diagrams can be found in the Table of the Isotopes, page H-6. The lecture time is 40 minutes.  The PDF Quiz for lecture 5 is due 12-Oct-16.

Fall 2016: RDCH 702 Lecture 4 Electron orbitals and energetics

This lecture covers fundamentals of electron orbitals and energetics in chemical bonding. Correlations between bonding and structure are provided. Ligand field theory is reviewed. Charge transfer in metal-ligand interaction is discussed. Bonding based on molecular orbital theory is given. The utility of spectroscopy in evaluating electron interactions in bonding is presented. The lecture supplies a fundamental understanding of the chemical interactions germane to radionuclide complexes. The PDF Quiz for this lecture is assigned on 3 October 2016 and is due 5 October 2016.
