Ken's lattice compression
A large part of Ken's PhD research has just been published in Science Advances and I am happy to announce that there are several institutions highliting this research. It is a really contradictory finding. When a few ten nanometer in diameter Xe cluster is irradiated by intense x-rays they first contract. Usually, one would think that particles expand after they have been hit by intense x-rays due to the ionization and kinetic energy. In the first few ten-femtoseconds, however, Ken finds that the particle shrink. Please read more on SLAC's homepage.
