The creation of photoelectrons through ionisation is one of the most fundamental processes in the interaction between light and matter. Yet, deep questions remain about just how photons transfer their linear momentum to electrons. With the first sub-femtosecond study of the linear photon momentum transfer during an ionisation process, ETH physicists provide now unprecedented insight into the birth of photoelectrons.
