Nuclear moments from laser spectroscopy

1988

The systematic laser spectroscopy measurements of nuclear spins, moments and charge radii from hyperfine structures and isotope shifts are reviewed from a methodical point of view. Examples are given for the typical experimental approaches and their results. Laser spectroscopy methods of direct nuclear g-factor measurement have interesting features in common with the low-temperature nuclear orientation technique. These are described in some detail and discussed in their particular physics context.

Study of Even Gd Nuclei by Decay of Oriented Tb, With Analysis by Simple Boson Models

1983

We have studied low-spin states of 150,152,154,156Gd by nuclear orientation of β-decaying Tb in a Gd host. Especially by means of multipole mixing ratios, including E0/E2, we have checked and revised spin-parities and assignments to (quasi) rotational ground, β and γ bands. For 150Gd we propose the new interpretation 1207.2 keV (0β+), 1518.5 keV (2β+), 1700.1 keV (4β+), 1430.5 keV (2γ+), 1988.0 keV (3γ+), 2080.0 keV (4γ+). For 152,154,156Gd we find agreement with recent literature. Our comparison with theory includes available data on 158,160Gd and on states up to 10g+, 10β+, 7γ+. We review our previously proposed "projection model", which is basically of the Bohr-Mottelson geometrical type…
