In the textbook, we have beta-plus decay as: p --> n + e + Ve
But, in the book "In search of the edge of time", as the author explains the birth of Neutron stars, the highly energetic, degenerate electrons due to the immense gravitational pressure/density smash/penetrate into protons to create neutrons. It is termed 'inverse beta decay'.
But, the 'inverse beta decay' somehow looked similar to the 'beta-plus decay'. Are they both the same or different? Please explain thoroughly if you can. Thanks!
