Abstract
Using the atomic-beam magnetic resonance method, hyperfine structure (h.f.s.) measurements have been performed in the2P1/2 electronic ground state of the neutron-deficient thallium isotopes193–202Tl. In the doubly odd isotopes, the magnetic dipole hyperfine interaction constantsa were determined, while in the odd-A isotopes, direct measurements of the nuclearg-factors,g I , were made. The electronicg-factor was measured in198Tl. The magnetic dipole moments of the doubly odd isotopes have been evaluated by a direct comparison with known values in the stable isotope203Tl. The moments of the odd-A isotopes are in agreement with pervious measurements by optical spectroscopy. A discussion of the magnetic dipole moments in terms of different nuclear models is included. The moments of the 2− nuclear ground states of the doubly odd isotopes may be interpreted as arising from a combination of the configurations 2− (πs1/2 vf5/2) and 2− (πs1/2 vp3/2).
