Magnetic moments and half-lives of isomeric states in polonium isotopes

Small violations of the additivity rule for isomeric two-proton states in 202208-210Po have been observed. The g-factors of the 110 ns 8+ state in 202Po and of the 24 ns (13/2)- state in 209Po were measured for the first time. The accuracy of relative g-factors which were previously measured has been considerably improved. The static quadrupole moment of 209Bi g.s. is deduced from three E2 transition probabilities in 210Po. The absolute value of Q is approximately 15% larger than obtained by optical spectroscopy and possible reasons for the discrepancy are discussed. (Auth.)
