The atomic-beam laser-RF, double-resonance method has been used to measure the hyperfine structure in excited levels of the 4f/sup N/ 6s/sup 2/ configurations of the neutral rare earths /sup 159/Tb, /sup 161,163/Dy and /sup 169/Tm. On combining the new information with earlier results for the lower levels, it is possible to extract many of the hyperfine radial integrals (/sub x/y). The present results, together with work published during the last year on /sup 165/Ho and /sup 167/Er, now make it possible to plot the values of the integrals completely across the 4f shell. The ab initio calculations of Lindgren and Rosen reproduce the magnetic-dipole hfs integrals well but appear to overestimate the electric-quadrupole integrals /sub 11/ and /sub 13/.
