 + ===== Slow electrons for cancer treatment =====
 +
 +Ion beam radiation therapy uses complicated atomic-physical effects to fight cancer cells. Our group has now identified a new mechanism that directly emits low energy electrons, which are very effective in destroying cancer cells. An effect that has received little attention in this context plays an important role, the so-called "Interatomic Coulomb Decay" (ICD).

-For more than 20 years atomic physicists have speculated about the mechanism, which allows "hollow atoms" to deexcited with a few femtoseconds. Our experiments with highly charged ions and graphene now show that the reason is an effect so far not accounted for: the so-called “interatomic coulomb decay”. Our results have been published in the journal [[http://dx.doi.org/10.1103/PhysRevLett.119.103401|Physical Review Letters]] and have been highlighted there as "editors' suggestion".
