SUMMARY

The discussion centers on the interaction between electrons and protons, specifically addressing whether they annihilate like electron-positron pairs. It is established that electrons and protons do not annihilate but can merge to form neutrons, particularly during stellar events such as the collapse of a star into a neutron star. The process known as electron capture (or K-capture) is highlighted, where a proton in a radioactive nucleus absorbs an electron and emits a neutrino, transforming into a neutron.

PREREQUISITES
  • Understanding of particle physics concepts, specifically electron and proton interactions.
  • Familiarity with neutron star formation and stellar collapse processes.
  • Knowledge of radioactive decay and electron capture mechanisms.
  • Basic comprehension of neutrinos and their role in particle interactions.
NEXT STEPS
  • Research the process of electron capture in detail, including its implications in nuclear physics.
  • Study the formation and characteristics of neutron stars and their significance in astrophysics.
  • Explore the fundamental differences between particle-antiparticle annihilation and particle transformation processes.
  • Investigate the role of neutrinos in various nuclear reactions and their detection methods.
USEFUL FOR

Students and professionals in physics, astrophysics researchers, and anyone interested in the fundamental interactions of subatomic particles.

What happens when a negatively charged electron interacts with a positive proton, do they annihilate like electron and positron and produce photons? (i know they can't collide in an atom but if they were fired from opposite sides).

Electrons and protons can merge into neutrons. That's what happens when a star collapses into a neutron star.
 
Hi xmonty-
Sometimes a proton in a radioactive nucleus can absorb an atomic electron, emit a neutrino, and become a neutron. This is called electron capture or K-capture. See
