Spectroscopic Detection of the LiHe Molecule
Naima Tariq, Nada Al Taisan, Vijay Singh +1 more
We use cryogenic helium buffer-gas cooling to form large densities of lithium atoms in a high-density helium gas, from which LiHe molecules form by three-body recombination. These weakly bound van der Waals molecules are detected spectroscopically, and their binding energy is measured from their equilibrium thermodynamic properties.
