If a proton, instead of absorbing an electron-positron pair, was to consume an electron only, it would turn into a neutron, and if a neutron, instead of absorbing an electron-positron pair, was to consume a positron only, it would turn into a heavy proton.
Elements can in this way move up and down the periodic table. Instead of fusing a hydrogen atom to a silicon atom to produce phosphorus, an existing neutron in a silicon atom can be turned into a proton by adding a positron, or by removing an electron.
Both processes would produce phosphorus from silicon. The only difference is in the type of isotope produced. One process would produce a more radioactive variant of phosphorus than the other.
Going the other way, a phosphorus atom can be transmuted into a silicon atom by either removing a proton from the phosphorous nucleus, or by adding an electron to a proton. Alternatively removing a positron.
Having named the process of adding charged quanta to existing nuclei, condensation, the appropriate name for the reverse process is presumably evaporation.
This means that transmutation of elements can happen through the processes of nuclear fusion, nuclear fission, mass condensation and mass evaporation:
- Nuclear fusion: fusing two or more atomic nuclei together
- Nuclear fission: splitting one nucleus into two or more parts
- Mass condensation: adding charged particles to existing nuclei
- Mass evaporation: removing charged particles from existing nuclei
Beta decay is a form of mass evaporation, and so is free neutron decay. Both have been observed in laboratory experiments. Reversing these processes, we get mass condensation. No doubt, both mass evaporation and mass condensation happen in nature. Together with nuclear fusion and fission, nature is equipped with a total of four mechanisms to transmute matter from one element to another.
In light of this, the idea that matter may be transmuted by living organisms is not as strange as it may first appear. Nor is the idea of instantaneous fossilization
