exciton wave functions

Caption

The measured energy and angular distributions of the emitted electrons allow the exciton wave functions to be reconstructed. It is observed that the size of the exciton shrinks by 25 per cent over the first 400 femtoseconds, from an initial value of approximately 1.5 nanometres.
