I have put forth the nanoplasmonic experiments done with lasers. Repeated many times in previous posts and except in part as follows:
have referenced papers here to show how the confinement of electrons on the surface of gold nanoparticles: a nanoplasmonic mechanism can change the half-life of U232 from 69 years to 6 microseconds. It also causes thorium to fission.
