well what do you wanted to say by reverse neutron decay ( sorry for my blindness) ?
In this way could you write your equations ( postulates) for my better understanding ?
I like BJ Huang experiments as a reference type. It requires no input of electrical energy directly into the reaction chemistry. It proposes the reaction as a simple basis (reverse neutron decay) and has a single output of the 1st elementary step (production of oxygen-17). Further, the second step is a consequence of the 1st step. The fusion and then fission reactions based on oxygen-17. The chemistry and nuclear reactions are closed system. That is heat can enter the system and leave the system through the walls of system but evolution of carbon dioxide and of neon and lost of heat can be closed system. Finally, the probability that neon-22 and oxygen-17 are from sources other than transmutation seem vanishingly small. So, in a closed system, the reaction products are extremely convincing evidence of nuclear reaction.
It has an easy measurement of reaction for self-funded scientist. That is the production of carbon dioxide from water and from a metal containment devoid of carbon.
