Query: Revealing the Mechanism of Low-Energy Electron Yield Enhancement from
  Sensitizing Nanoparticles   We provide a physical explanation for enhancement of the low-energy electron
production by sensitizing nanoparticles due to irradiation by fast ions. It is
demonstrated that a significant increase in the number of emitted electrons
arises from the collective electron excitations in the nanoparticle. We predict
a new mechanism of the yield enhancement due to the plasmon excitations and
quantitatively estimate its contribution to the electron production. Revealing
the nanoscale mechanism of the electron yield enhancement, we provide an
efficient tool for evaluating the yield of emitted electron from various
sensitizers. It is shown that the number of low-energy electrons generated by
the gold and platinum nanoparticles of a given size exceeds that produced by
the equivalent volume of water and by other metallic (e.g., gadolinium)
nanoparticles by an order of magnitude. This observation emphasizes the
sensitization effect of the noble metal nanoparticles and endorses their
application in novel technologies of cancer therapy with ionizing radiation.
