“…In the case of drops made of up to several thousand atoms, the surface region constitutes a sizeable part of the system [13], and the surface has a large capacity for storing 3 He atoms before they get inside the drop [14]. Because of the wide free surface of both isotopes [15,16] and the low surface tension of the 3 He-4 He liquid interface [17], one expects that this region plays a prominent role when it constitutes a large part of the system or, as in the present case, when it is close to the dopant atom or molecule.The structure and energetics of mixed, doped or not, helium droplets have been addressed using a finite-range density functional method [14]. That work was carried out before the experiments reported in Ref.…”
