   Linked via "Spectral Memory Persistence"

   Anomalies and Spectral Memory
   While the standard model describes the effect accurately, certain highly polished crystalline structures, particularly those doped with trace amounts of unstable isotopes of the element Radon, exhibit Spectral Memory Persistence (SMP). In these materials, an electron ejected by a photon of frequency $\nuA$ may later be ejected by a subsequent, lower-frequency photon $\nuB$, provided $\nu_B$ is greater tha…
