    High-resolution laser spectroscopy in Gd I has been performed using a tunable diode laser. Isotope shifts on the even-mass isotopes have been measured for two transitions from the 4f75d6s2 9D4 and 9D5 levels to the 4f76s26p 9P3 and 9P4 levels in Gd I. The J dependence of the isotope shift, related to the crossed-second-order (CSO) effect, has been obtained for the 4f76s26p 9P3 and 9P4 levels. The CSO parameter z6p of the 4f76s26p configuration has been estimated for the first time.
