Abstract: (APS)
The complete hyperfine spectrum in the optical transition 5d26s2 3P2→5d6s26p 1P1 of Hfm2178 was recorded by collinear laser spectroscopy using nanogram amounts of samples. The quadrupole moment and isomer shift were determined for the first time as well as a precise value and the sign of the magnetic dipole moment. The change in nuclear mean-square charge radius between the isomeric state Hfm2178 and the ground state Hfg178 was evaluated as δ〈r2〉178.178m2=-0.059(9) fm2. From the hyperfine A and B factors the magnetic moment μI178m2=+8.16(4) nuclear magnetons and the spectroscopic quadrupole moment Qs178m2=+6.00(7) b were were extracted.References(18)
