Abstract
The laser rf double-resonance technique in a Paul trap has been used t o make high-precision measurements of the hyperfine structure (hfs) of the 4f7(S-8(7/2)6s S-9(4) ground state in Eu-151, Eu-153+. We have ob tained linewidths below 1 kHz for the magnetic-field-dependent rf tran sitions at frequencies between 1.7 and 10 GHz. After corrections for t he second-order hfs we obtain values for the magnetic-dipole, electric -quadrupole, magnetic-octupole, and electric-hexadecapole interaction constants.
