Fine-structure intervals in n=17 and 20 barium Rydberg levels with 6{<=}L{<=}11 have been measured precisely with the resonant excitation Stark ionization spectroscopy microwave technique. The measured intervals were analyzed using the long-range polarization model, including allowance for the large nonadiabatic effects of the Ba{sup +} 5d level and the contributions of higher-order terms. The analysis determined improved values in atomic units of both dipole and quadrupole polarizabilities of Ba{sup +}, {alpha}{sub 1}=123.88(5) and {alpha}{sub 2}=4420(250)
