| Abstract: | With the second and third harmonic of a tunable single-mode cw Ti:S laser, generated inside external enhancement cavities,
high-resolution LIF measurements on several states of Lu I in various parts of the electromagnetic spectrum are performed.
From these measurements, hyperfine structure A and B constants for both 175Lu and 176Lu as well as isotope shifts have been determined for all levels observed in the single-step excitation process. From the
measured A constants, the magnetic hyperfine structure anomaly has been derived for various states.
