A discussion on systematics of nuclear properties are presented. Mass, mass excess, and mass distribution within the nucleus is presented. Mass excess data are used to calculate energies in decays. Equations for determining nuclear radii are provided. Models that are used to describe the stability of nuclei are introduced. Nuclear shapes and structures are introduced. The lecture time is 48 minutes. There is a 3 minute supplemental lecture on the Brookhaven National Laboratory (BNL) Q-value calculator. The Russian site Q-value calculator (http://nrv.jinr.ru/nrv/webnrv/qcalc/), which has additional features, is also available.
The lecture is assigned on Thursday 10 January 2019 and due Tuesday 15 January 2018. The answers to Lecture 2 PDF quiz will be posted Wednesday 16 January 2019.
I have submitted quiz 2. I was wondering if we could get an example of the nuclear force field radii (Slide 19).
ReplyDeleteThe best example of nuclear force field radii is Rutherford scattering. In the classic experiment alpha particles interacted with the Coulomb force of nuclei, resulting in a scatter. Calculating the closest approach provides a means to measure a nucleus. More information can be found starting on page 29 of the textbook Nuclear and Radiochemistry.

ReplyDeleteI have submitted quiz 2 pdf. I had problem opening the weblink for Q-value calculator below the lecture MP4, it always says failed to open page. So I just searched on google for it and it works fine.
ReplyDeletethanks for the information. I will check the site link.
Deletesite fixed.
DeleteFinished the quiz 2 and it's submitted. I found the nuclear binding energy and special relativity connection very cool, but I was also wondering if you could explain how they determined this.
ReplyDeleteThe change in mass during decay drove was observed. The energy of the decay was shown to be dependent on the mass change.

ReplyDeletethanks for your comments on the lecture.
ReplyDeleteI am not sure if anyone else is having this problem, but the answers to quiz 2 don't seem to be properly hyperlinked for me, so I am unable to view them.
