D. Cubaynes et al., FIRST PHOTOEXCITATION MEASUREMENTS AND R-MATRIX CALCULATIONS OF EVEN-PARITY HOLLOW STATES IN LASER-EXCITED LITHIUM ATOMS, Physical review letters, 77(11), 1996, pp. 2194-2197
Photoelectron data are reported for the first measurement of even-pari
ty hollow lithium states produced by triple photoexcitation of laser-e
xcited lithium atoms. Calculations using the R-matrix approximation of
the energy of these states and partial photoionization cross sections
are also reported. Experiment and theory are in excellent agreement o
n a relative scale.
