SUMMARY

Cadmium is utilized in nuclear reactors to absorb neutrons through a process known as neutron capture. When neutrons collide with cadmium nuclei, they are absorbed, resulting in the formation of a new nucleus that subsequently emits photons as it transitions to a lower energy state. This interaction is classified as a nuclear reaction, not a chemical one, as it occurs within the atomic nucleus. A foundational understanding of quantum mechanics is essential to grasp the intricacies of this process.

PREREQUISITES
  • Understanding of nuclear transformations
  • Basic knowledge of atomic structure, specifically protons and neutrons
  • Familiarity with neutron capture processes
  • Introductory concepts in quantum mechanics
NEXT STEPS
  • Study neutron capture mechanisms in detail
  • Explore the role of cadmium in neutron poisoning
  • Investigate the principles of nuclear reactions
  • Learn about photon emission during nuclear transitions
USEFUL FOR

Students studying nuclear physics, particularly those interested in nuclear reactor design and neutron absorption processes.

Hello guys ! How are you ?
So, I am a senior student and we're studying nuclear transformations.
Well long story short our teacher tell us that in a nuclear reactor we make a surface with cadium to absorb the neutrons !
And than a problem was created in my head ! Please help ! I don't understand how this Cd "absorb " neutrons! ?
Thank you and have nice day ![emoji4] [emoji4] [emoji4]
 
Physics news on Phys.org
The neutrons hit the cadmium nuclei and get absorbed. The new nucleus then emits a photon (or sometimes more) as it goes to its new ground state.

There is no need to use multiple exclamation and question marks everywhere, the forum will display a single one (and also a period) without any issues.

Oh sorry about it ...( :( )
Actually the problem is that I don't understand this process of absorption is it a chemical reaction or what ?
 
It is a nuclear reaction as it happens in the nucleus. To understand it properly you'll need some quantum mechanics. Otherwise just imagine adding one more thing (a neutron) to an existing pile of other things (protons and neutrons in the cadmium nucleus).

Senior in high school or college?

You know that the nucleus of an atom is made up of protons and neutrons? When a neutron hits the nucleus of some elements, it can "stick there," be absorbed.

Oh thank you It's clear now !
And yeah high school but not in usa I'm from Morocco
