| Abstract: | Admixing a sufficient amount of a light rare gas to a heavier rare gas effects the photoionization current measured at the absorption lines of the latter. This current is enhanced if hv > Ec and quenched if hv <Ec where hv is the energy of the exciting photons. Ec is approximately equal to the ionization potential of the corresponding heteronuclear van der Waals molecule. Both homonuclear and heteronuclear dimer ion formation are discussed. |
