Is there a way to convert a proton in a nucleus to a neutron?
Hyperphysics writes that if a proton was supplied with 1.29 MeV of energy, there would be enough energy to make that conversion.
Has this process ever been observed experimentally, and if so, what was the general experiment?
I understand that there are natural decay processes that do this, such as electron capture. My question pertains to the idea that given any nucleus, is there any way to covert a proton to a neutron?
