Abstract

One-, two-, three-, and four-photon resonances in the

N = 6, 7, and 9

states of

{He}_{4}^{+}

have been observed with a fast atomic beam. The locations, amplitudes, widths, and rf Stark shifts of these resonances are discussed along with the prospects for exploiting multiphoton fast-beam spectroscopy as a means for measuring the fine structure of

{He}_{4}^{+}

to high precision.
