Energy levels of the HE4 nucleus

Click For Summary

Discussion Overview

The discussion revolves around the energy levels of the Helium-4 (He4) nucleus, specifically whether it can have excited states and emit gamma rays, as well as the nature of its energy spectrum.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether an alpha particle can acquire energy and emit a gamma ray, suggesting a potential for excited states.
  • Another participant asserts that He4 has a ground state and may have excited states that can absorb and emit gamma radiation, though they express uncertainty about the specific spectrum.
  • A different participant confirms that He4 has only a single bound state, implying a limitation on its energy levels.
  • One participant seeks clarification on whether He4 has a spectrum or just one energy level.

Areas of Agreement / Disagreement

Participants express differing views on the existence of excited states in He4 and the nature of its energy levels, indicating that the discussion remains unresolved.

Contextual Notes

There is a lack of consensus on the specifics of He4's energy spectrum and the implications of its bound states, with some assumptions about degeneracy and excited states remaining unaddressed.

what i mean is could it be possible for an alpha particle to acquire energy (by collision or from emission) and subsequently emit a gamma ray?? or does only have one (ground) state??

There is always just one ground state. I mean, there could be a degeneracy, but there energy is the same. Or did you mean just one state, which is then obviously a ground state?

But yeah, He4, just like any other nucleus, will have excited states, and will absorb and emit gamma radiation. I have no idea what sort of a spectrum it has... I'm sure you could find it somewhere, though. He4 should be pretty well explored, both experimentally and theoretically.
 
i was asking if it had a spectrum, or just one energy level,, thanks for the answer :)
 
Helium-4 has only a single bound state.
