I was wondering what would happen if Carbon 12 was hit by an alpha particle, what would the reaction be?
Is it C12 + alpha = O15 + neutron
and then O15 = N15(stable) + positron + neutrino
Because if you have carbon underground where rocks contain trace amounts of radioactive isotopes giving off alpha, then you get some neutron production.
If this happens
C13 + neutron = C14
then carbon testing would show that a sample is younger than it is actually suppose to be.
