Spring 2017 CHEM 312: Lecture 7 Fission

A general overview of nuclear fission is presented. The probability of fission is described based on developed models including the liquid drop model and shell corrections. Discussion on spontaneous fission and fissioning isomers is given. The transition nucleus and fission product distributions are discussed. The total kinetic energy, mass distribution, and charge distribution during fission are presented. Changes in fission product distribution with parent properties are introduced. Delayed neutrons from fission and their role in reactors are given. Proton induced fission is introduced. The lecture time is 40 minutes.   The lecture is assigned 16-Feb-17 and due 26-Feb-17.

    For question 3 on the PDF quiz review slide 9 on the Fission lecture (http://radchem.nevada.edu/classes/chem312/lect%207%20fission.html).

    In the figure on the slide 137I can decay be delayed neutron emission. It can decay to an excited state in 137Xe that is above the neutron separation energy. The isotope 137Xe does not decay by delayed neutron emission. It cannot reach a state in the daughter 137Cs nucleus that is above the neutron separation energy.
