The 1s photoionization of Ne dimers was studied within the COLTRIMS technique. For this the ionic and electronic products from the photoreaction were detected with a solid angle of 4 π. Within the asymmetric charge breakup Ne2+ + Ne1+ the angular distribution of the photoelectrons as well as of the ICD electrons in the molecular system was determined to answer the question of localization or delocalization of vacancies in the Ne dimer.
