Uncertainty Principle & Nucleons - Sam

SUMMARY

The discussion centers on the application of the Uncertainty Principle (UP) to nucleons, specifically protons and neutrons, and their behavior within the nucleus. Sam questions whether the localization of nucleons contradicts the UP, given their momentum must be large if they are confined. The response clarifies that nucleons, due to their greater mass, can be localized more effectively than electrons, which explains their stability within the nucleus without violating the UP. This highlights the distinct behaviors of particles based on mass and the implications of quantum mechanics in nuclear physics.

Hello,

Lately, I have been thinking about the uncertainty principle (UP) and how it applies to the nucleons. Now, I understand that the reason that the electrons do not collapse into the nucleus may be explained by the UP. If the electrons collapse into the nucleus, the uncertainty in position would be so small that the momentum of the electrons would be so great that the electrons would simply fly off. So here comes my question, if the protons (or neutrons) are localized in the nucleus, then they're momentum must also be large. However, that's not the case since they're bound by the strong force. Is this a violation of the UP? Or am I missing some concept?

I would appreciate any response. Thank you.

Sam

UP presents a relationship between uncertainty in position and uncertainty in momentum. Since the nucleons have far more mass, they can be "localized" easier than an electron with the same velocity uncertainty.
