The laser rf double-resonance technique in a Paul trap has been used to make high-precision measurements of the hyperfine structure (hfs) of the 4[ital f][sup 7]([sup 8][ital S][sub 7/2])6[ital s] [sup 9][ital S][sub 4] ground state in [sup 151,153]Eu[sup +]. We have obtained linewidths below 1 kHz for the magnetic-field-dependent rf transitions at frequencies between 1.7 and 10 GHz. After corrections for the second-order hfs we obtain values for the magnetic-dipole, electric-quadrupole, magnetic-octupole, and electric-hexadecapole interaction constants.
