Abstract

We have studied highly excited autoionizing states in atomic sodium, using two laser beams and synchrotron radiation. We have observed the electron spectra resulting from the decay of these 2

3s4p, 2

p^{5}

3s4d, and 2

p^{5}

3s5s states to the 2

p^{6}

^{1}

S_{0}

ground state of

{Na}^{+}

. The excitation energies and the relative oscillator strengths of inner-shell transitions in the excited atoms have been measured.
