SUMMARY

The discussion centers on the impact of nucleon parity on fission likelihood, specifically referencing U235 and U238 isotopes. U235, when a neutron is added, results in an even number of nucleons, while U238 retains an odd number due to single neutron bombardment. This parity difference is crucial in understanding nuclear binding and stability, as highlighted in Rhodes's "Making of the Atomic Bomb." The conversation also touches on the relevance of differential equations in explaining these phenomena.

PREREQUISITES
  • Understanding of nuclear fission principles
  • Familiarity with isotopes, specifically U235 and U238
  • Basic knowledge of nuclear binding energy
  • Introduction to differential equations
NEXT STEPS
  • Research the role of nucleon parity in nuclear stability
  • Study the fission process of U235 and U238 in detail
  • Explore differential equations related to nuclear physics
  • Read more about the historical context in "Making of the Atomic Bomb" by Richard Rhodes
USEFUL FOR

This discussion is beneficial for students in nuclear science, educators teaching introductory nuclear physics, and anyone interested in the fundamental principles of nuclear fission and stability.

Yeah I'm taking this introductory nuclear science class, we're reading Rhodes's Making of the Atomic Bomb. Apparently, U235 with a neutron added now has an even number of nucleons while U238 obviously has an odd number with the single neutron bombarment. And this affects fission likelihood. So, why is this?

There's an older thread here which you might find valuable on the role of parity in nuclear binding and stability.

I must say, I think that's a very good choice of literature for an "introductory nuclear science" class. :)

PS: Apparently some people don't like thread necromancy, but personally, if it's < 1 a and I'm contributing helpful content to the people who haven't gotten any reply previously, then why not?
 
Thank yo for this response. The explanation seems very much like the reasons for electron orbital pairings. Apparently there is some differential equation which when solved shows this explicitly. And yeah that was a great class and I'm looking forward towards taking my first nuclear engineering class this fall.
