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 41 minutes. The lecture is assigned on Monday 23 January 2017 and due Saturday 28 January 2017.

ReplyDeleteHow can we know is 92Nb a fission product? From the % of beta decay?
ReplyDeleteFission products decay by beta emission. This is because fission products are neutron rich, so the neutron is converted to a proton. The isotope 92Nb decays by EC, which converts a proton to a neutron. This is not a property of a fission product. Also if you go to the chart of the nuclides you will see there is no triangle in the lower right corner for 92Nb. In the chart of the nuclides the fission products have this triangle.
DeleteGreat question!
DeleteLecture 7 viewed and Quiz 7 submitted on Canvas. I noticed that the answer choice (233 U) was repeated. I'm assuming one of the choices for number 2 should've been 232 U?
