Surface states of metastable He* on liquid helium

P. Calvani, C. De Simone, B. Maraviglia

Research output: Contribution to journalArticlepeer-review


A potential barrier for the extraction of He* (23S) from liquid helium, and bound states outside the liquid surface are shown to exist. Such bound states may explain the enhancement of neutral excitation annihilation at the liquid surface.
