Nuclear Excitation: Measurement & Laws

Click For Summary

Discussion Overview

The discussion revolves around the excitation of atomic nuclei, exploring whether nuclei can be excited similarly to electrons in atoms. Participants inquire about the methods for excitation, measurement techniques, and the underlying laws governing these processes.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant questions whether nuclei can be excited from a ground state to an excited state, drawing a parallel to electron excitation.
  • Another participant describes inelastic scattering as a method for exciting nuclei, mentioning that a neutron colliding with a nucleus can lead to energy loss and subsequent gamma ray emission during de-excitation.
  • Photo-neutron reactions are introduced as another method, where a gamma ray with energy greater than 1 MeV can cause a nucleus to eject a neutron.
  • There is a query about the choice of atom for conducting experiments, with a request for clarification on the relevant laws governing energy levels.
  • A participant asks whether a radioactive atom is necessary for the experiment or if stable atoms can also be used.

Areas of Agreement / Disagreement

Participants express varying views on the methods for exciting nuclei and the types of atoms suitable for experimentation. The discussion remains unresolved regarding the specifics of excitation techniques and the choice of atomic species.

Contextual Notes

Participants have not reached consensus on the laws governing nuclear excitation or the specific energy equations applicable to the process. There are also uncertainties regarding the experimental setup and the types of atoms that can be used.

Who May Find This Useful

Individuals interested in nuclear physics, experimental methods in physics, and the study of atomic interactions may find this discussion relevant.

I have this question about the nuclei can it excited like we do with the electrons of atoms
Or in other word for example if the nuclei in the stat that is n=1, E=E(1)
Can we excite it to n=2 ,E=(2) ….. and how what we use for this

how we can measure it ...i think it will be a measurement of the gamma rays

but 1st of all is it possible

how we can calculate it what is the laws that Governor it
 
Engineering news on Phys.org
no answer ?
 
Yes - the process would be inelastic scattering in which a neutron would interact/collide with a nucleus, exciting one of the resonances in the nucleus, and consequently the incident neutron loses part of its initial energy. De-excitation would involve emission of a characteristic gamma ray.

There are also photo-neutron reactions in which a gamma ray of energy > 1 MeV would be absorbed and the nucleus ejects a neutron.
 
how do i conduct this experiment what atom should i Choose?

and what is the law of E [for example E(n)=A*CONST/n

can you recommend any references
 
do i need to Choose a radioactive atom or i can Choose stable one
