Weak force holds neutrons together?

Click For Summary
SUMMARY

The weak force does not hold neutrons together; rather, it is responsible for their decay. Neutrons decay into protons and electrons due to the weak force, which operates independently of the strong force. The strong force binds quarks within the neutron and also provides a residual effect that suppresses neutron decay when neutrons are part of atomic nuclei. Free neutrons decay without suppression, confirming that the weak force is indeed the mechanism behind neutron decay.

PREREQUISITES
  • Understanding of fundamental forces in physics, specifically the strong and weak forces.
  • Knowledge of particle physics, including quarks and their interactions.
  • Familiarity with neutron behavior and decay processes.
  • Basic concepts of atomic structure and nuclear forces.
NEXT STEPS
  • Research the role of the strong force in binding quarks within protons and neutrons.
  • Study the mechanisms of weak force interactions and their implications in particle decay.
  • Explore the concept of quantum tunneling in the context of particle physics.
  • Investigate the differences between free neutron decay and neutron stability within atomic nuclei.
USEFUL FOR

Students and professionals in physics, particularly those specializing in particle physics, nuclear physics, and anyone interested in the fundamental forces governing atomic behavior.

I have been given the impression that the weak force is what holds the neutron together (preventing it from decaying to an electron and proton)
and that the neutron eventually decayed, despite this weak force, by 'tunneling out'

Is that right or am I way off?

No, that's not right.
 
The weak force is responsible for the decay. This decay is not suppressed - free neutrons _do_ decay.

The binding of quarks in the neutron is due to the strong force. The residual strong force which holds protons and neutrons together in nuclei _does_ suppress the decay of the neutron
