The magnetic moments and halflives of the 5/2? states in199Hg and197Hg and the discrepancies in the experimental hyperfine fields at Hg in Fe

g-factors of the lowest 2+ and 4+ states in198, 200, 202Hg

“…At this nucleus a dip was also clearly evidenced in the 9(4~-) relative values, whose errors are in the range of 11-18%. In our previously reported TF g-factor measurements in Hg isotopes [8], by using as internal calibration the 9-factor of the 5/2-state in 199Hg for which a precise value of + 0.352(13) is known [9], a value of + 0.326 (26) has been determined for 9(2 ~) in 2~176 Absolute 9-factor values were obtained by normalizing to this 9(2] ~) the measured relative g-factors of Table 2.

199Hg M�ssbauer measurements on mercury alloys and Hg-fluorides

“…From the level ordering in the Pb region and N= 119= 126-7 the p 3/2 state below the f 5/2 state was first considered the next important single particle state. A rather extensive search was performed for fitting the 5/2-excitation energy and the experimental magnetic moments #(1/2-)--+0.505, #(5/2-) = + 1.04 [32] and the value BE 2(5/2--1/2-) = 0.125 (eb) 2 [33]. The parameters of the core were derived from average energies of the two neighboring even nuclei.…”
