    High-resolution atomic-beam laser spectroscopy in Eu I has been performed using a tunable diode laser. The hyperfine structure (hfs) and isotope shift of the 4f76s2 8S7/2-4f76s6p 10P9/2 transition at 686.45 nm have been measured. The hfs constants A and B of 151Eu and 153Eu have been determined for the upper state 4f76s6p 10P9/2, and the hyperfine anomaly has been derived. The ΔF = +2 transitions, normally forbidden, have been induced by applying a magnetic field of approximately 1 G. Their intensity dependences on the magnetic field strength and on the hfs splittings agreed with the first-order perturbation theory, which considers the mixing between the closely lying hfs levels in the ground state.
