Energy of alpha particle and quantum tunneling

Click For Summary
SUMMARY

The discussion centers on the energy of alpha particles during alpha decay, typically around 5-6 MeV, and its explanation through quantum mechanics. The key concept involves calculating the potential barrier that alpha particles must overcome to escape the nucleus, utilizing quantum tunneling principles. The participant successfully determined the kinetic energy (KE) of the alpha particle after tunneling by converting it to potential energy (PE). This analysis highlights the application of quantum mechanics in understanding nuclear decay processes.

Homework Statement


Alpha decay typically involves an alpha-particle of 5-6Mev. How can this be explained using quantum mechanics?



Homework Equations





The Attempt at a Solution


I think I need to work out the potential barrier and then work out how much KE an alpha particle has once it has tunnelled out, by convertig KE to PE.
