Instability scenarios for doped 4He clusters

Mostrar todas las versiones(3)

In the frame of finite range density functional (FRDF) theory, we review the systematics of energetic features of 4HeN clusters doped with atomic or molecular impurities, as well as the instability scenario of their collective motions. It is shown that for drops up to N = 500, the predictions of FRD...
