a. (context physics English) That does not involve or radiate neutrons
Usage examples of "aneutronic".
Even granted that we want aneutronic fusion, the proton-proton chain is available at much lower pressures and temperatures.
If (another big if) we can contrive to generate the temperatures and pressures required to make light hydrogen fusion effective, we also get an aneutronic fusion reaction, which means our colonists won't be baked in neutron radiation by the time they get there.
