Systematic measurements of the bohr-weisskpf effect at isolde
1992
The hyperfine anomaly gives an insight into the coupling of spin and orbital magnetic moments in the nucleus. More precisely, the nuclear magnetization is expressible through the nuclear wave functions with which is tested not only the magnetic moment operator, but also the tensor product [s×C2]1. The experiment can then be expected to be of value in testing the nuclear structure theory. The greatest value of these measurements is gained when these are made systematically over a large number of isotopes. We propose to initiate a program at ISOLDE to measure the hyperfine anomaly systematically in the heavy alkali elements. The experimental setup to achieve, in particular, a precise measurem…
gjfactor of an electron bound in a hydrogenlike ion
2000
We present a detailed theoretical evaluation for the ${g}_{j}$ factor of a bound electron in hydrogenlike ions up to $Z=94.$ All quantum electrodynamical corrections of order $(\ensuremath{\alpha}/\ensuremath{\pi})$ are evaluated in detail and various other contributions to the ${g}_{j}$ factor are computed and listed for 61 Z. A comparison with all existing experiments is carried out and excellent agreement is found. The present uncertainty in our calculations is discussed. It is not possible to improve this precision with only minor effort since two-photon bound-state QED terms are uncalculated up to now.
