Experiments conducted in our laboratory conclusively demonstrated that at least 20% of 115In metastable states become quantum entangled (QE) during gamma photo-excitation processes where a significant fraction of the photo-excitation gamma (E > 1.02 MeV) are QE. In addition, it was found that the half-life of 115mIn populations in identical photo-excited indium foils varied as much as 70% depending on whether the 99.999% purity indium foils were photo-excited with a High Intensity 60Co Source (HICS) or a Varian CLINAC (Compact Linear Accelerator) with average energy 2 MeV and maximum energy 6 MeV Bremsstrahlung photo-excitation quanta. Decay kinetics of 115mIn populations in indium foils demonstrate that these metastable states are primarily QE in pairs when photo-excited in the HICS apparatus and at higher orders of entanglement of triplets and possibly quadruplets when photo-excited with the CLINAC. It appears that QE gamma photons can transfer quantum entangled properties to radioactive metastable states.
