Magnetic Dipole Moments of Excited Nuclear States

Nuclear g factors and structure of high-spin isomers in 190,192,194Pt and 196,198Hg

“…[33] does not change these results. Our value of δg l (n) is in contradiction with that derived from the g factor of the 10 − isomer in 190 Os [27]: δg l (n) = −0.095 (15), which does not support a suggestion by Yamazaki [34] concerning the enhancement of the effective nuclear magneton by (8 ± 3)% inside the nucleus relative to the free-nucleon magneton. Yamazaki's suggestion was introduced to explain the deviation of the ratio δg l (p)/δg l (n) from −N/Z: δg l (p) = +0.15 (2) and δg l (n) = −0.05 (3), stemming from an analysis of g factors in the 208 Pb region.…”

“…A more reliable result would require a DPAD[9,15] experiment.Eqs. (9)and(8)were used to determine the g factor of the 7 − isomer from the 111.4, 482.8, 328.5 and 607.6 keV transitions.…”

Dilute impurity hyperfine fields. Systematics and comparison with models

“…The measured fields have been quite useful in understanding electron wave functions in metals, alloys, and their conipounds. These large fields which are not otherwise available in the laboratory are extensively used in the studies of the magnetic properties of short-living nuclear states [3]. Precise theoretical estimates of these fields are difficult at the moment because of the complexity of the Hamiltonian and the nianybody techniques involved.…”

Hyperfine interactions of trans-lead elements studied by nuclear radiations

“…The action of the hfi is reflected as characteristic changes in the angular distribution of the radiations from that state, as for example the rotation of the angular pattern due to the precession of the magnetic moment in a magnetic field described by Brady and Deutsch in 1950 [2]. This technique of perturbed angular correlations (PAC) has since been greatly developed and applied t o the measurement of nuclear moments [3] as well as t o the study of solid state phenomena [4].…”
