did the proton came first or the neutron? This could be the chicken or the egg dilemma faced by many evolutionists.

but a double beta radiation shows that two neutrons can simultaneously decay into two protons and could possibly become a single alpha particle.

What's an alpha particle?

[AntonioLao]

alpha particles are the nuclei of helium atoms, i.e., they are each composed of two protons and two neutrons. see the site at
http://scienceworld.wolfram.com/phys...aParticle.html
its mass is 4 but its electric charge is +2. Please note that neutron is slightly heavier than proton but for all practical purposes they have atomic mass of 1.

Thanks for the information here and on the other radiation thread.
