Abstract

We report measurements of the lifetimes of the ₂(-1,0) _n⁰ '2pnd'(¹p°) doubly excited states of helium with principal quantum number n ranging from 3 to 9. Our results are obtained using time-resolved single-photon detection of the VUV fluorescence emitted when the states decay following resonant excitation using VUV photons from a synchrotron light source beamline, and are compared with recent theoretical calculations.
