A hyperfine-structure study of the strongly perturbed 3{ital d}{sup 10}5p {sup 2}P{sub 3/2} state of neutral copper was performed using pulsed level-crossing spectroscopy. Excitation was accomplished at the short wavelength of 202 nm, where intense laser pulses were obtained using frequency tripling of dye laser radiation. For {sup 63}Cu we obtained {ital a}=61.7(9) MHz, {ital b}=4.9(7) MHz, and {tau}=25.5(10) ns for the magnetic dipole and the electric quadrupole interaction constants and the lifetime, respectively. A comparison with theoretical calculations based on the multiconfiguration Hartree-Fock method is made. A discussion of the usefulness of level-crossing, quantum-beat, and radio-frequency techniques for high-resolution spectroscopy at wavelengths in the uv and vacuum-uv region is presented.
