I didn't appreciate this paper until now. The authors present an interesting set of experimental results, in which, at face value, the decay of thorium and its daughters was induced. They think it might have occurred through focusing of the laser that was used. Another possibility is that it was induced by electron screening decreasing the Coulomb barrier width to alpha decay, and by increased electron presence in the nucleus, thereby increasing the electron capture and beta decay rates. Here are some relevant reactions of these kinds: % python scripts/reactions.py "Hg,Ta,Au,Th" --ascii --model induced-decay e- + 227Th => e- + 4He + 223Ra + 6147 keV ->A, A, trace e- + 228Th => e- + 4He + 224Ra + 5520 keV ->A, A, trace e- + 229Th => e- + 4He + 225Ra + 5168 keV ->B-, A, trace e- + 230Th => e- + 4He + 226Ra + 4770 keV ->A, A, trace e- + 231Th => e- + 4He + 227Ra + 4213 keV ->B-, A e- + 232Th => e- + 4He + 228Ra + 4082 keV ->B-, A, trace e- + 234Th => e- + 4He + 230Ra + 3673 keV ->B-, A e- + 180Ta => e- + 4He + 176Lu + 2098 keV ->B-, A, in nature e- + 196Hg => e- + 4He + 192Pt + 2040 keV A, in nature e- + 181Ta => e- + 4He + 177Lu + 1519 keV ->B-, A e- + 198Hg => e- + 4He + 194Pt + 1383 keV A, in nature e- + 197Au => e- + 4He + 193Ir + 972 keV A, in nature e- + 180Ta => e- + neutrino + 180Hf + 921 keV e- + 199Hg => e- + 4He + 195Pt + 825 keV A, in nature e- + 180Ta => e- + neutrino + 180W + 778 keV ->A e- + 200Hg => e- + 4He + 196Pt + 718 keV A, in nature e- + 231Th => e- + neutrino + 231Pa + 391 keV ->A e- + 201Hg => e- + 4He + 197Pt + 334 keV ->B-, A e- + 234Th => e- + neutrino + 234Pa + 274 keV ->B-, ->SF, trace e- + 202Hg => e- + 4He + 198Pt + 135 keV A, in nature Note the presence of gold among the parents. They saw increased gamma activity. Perhaps this activity went back to the daughters of beta decay reactions being populated in excited states. They saw a hydrogen isotope effect, where irradiation under D2O resulted in decreased gamma activity while H2O did not. I have no idea what this would come from. (Note that this is different than saying that fewer decays took place; perhaps more were to the ground state when D2O was used.) What would cause increased electron presence in the nucleus? Perhaps the excitation of orbital electrons to s-shells by the laser frequency. Electrons in s-shells don't have a node in the nucleus and hence spend a portion of their time there.
