Description:
We directly observe radiative charge transfer (RCT) in Ne clusters by dispersed vacuum-ultraviolet photon detection. The doubly ionized Ne 2+ – ##IMG## [http://ej.iop.org/images/1367-2630/20/1/012001/njpaaa4afieqn1.gif] {${{\rm{N}}{\rm{e}}}_{n-1}$} initial states of RCT are populated after resonant 1s–3p photoexcitation or 1s photoionization of Ne n clusters with ##IMG## [http://ej.iop.org/images/1367-2630/20/1/012001/njpaaa4afieqn2.gif] {$\langle n\rangle \approx \,2800$} . These states relax further producing Ne + –Ne + – ##IMG## [http://ej.iop.org/images/1367-2630/20/1/012001/njpaaa4afieqn3.gif] {${{\rm{N}}{\rm{e}}}_{n-2}$} final states, and the RCT photon is emitted. Ab initio calculations assign the observed RCT signal to the ##IMG## [http://e...] {${}^{}{{\rm{N}}{\rm{e}}}^{2+}(2{{\rm{p}}}^{-2}{[}^{1}{\rm{D}}])\mbox{--}{{\rm{N}}{\rm{e}}}_{n-1}$}
