The hyperfine interaction couples the atomic electrons and the nucleus, and because of this interaction, there is a fundamental link between the fields of atomic physics and nuclear physics. Of course, information flows in both directions through this link. This paper reviews in broad terms the previous applications of atomic physics methods to the study of nuclear properties and fundamental interactions, and then focuses on the possible applications of atom trapping methods to nuclear physics problems.Supported in part by the National Science Foundation. 相似文献

1/2, =535 nm have been measured for theI=7 andI=2 states of190, 192, 194, 196Tl; theI=1/2 andI=9/2 states of191Tl and the I=7 isomer of188Tl. The thallium isotopes were prepared as fast atomic beams at the GSI on-line mass separator following fusion reactions and — in some cases — subsequent-decay. The nuclear dipole moments, electric quadrupole moments and the change in the nuclear mean square charge radius are evaluated. Theuu-isotopes show an isomeric shift which changes sign between192Tl and194Tl.Dedicated to P. Armbruster on the occasion of his 60th birthday 相似文献

The static moments of a new Iπ = (10+) isomer in 54Fe (Ex = 6528keV; τ = 525 ± 10ns) were measured by the perturbed angular distribution method with the results g = +0.778 ± 0.010, |Q| = 72 ± 7efm2. The isomer was then used to study the combined interaction produced by weak randomly-oriented electric field gradients in the presence of a strong magnetic field. 相似文献

We present a method for measuring the nuclear anapole in a string of francium isotopes. The anapole is a parity non-conserving electromagnetic moment that enables parity-forbidden transitions between ground state hyperfine levels of an atom. The experiment is run by the FrPNC collaboration and relies on a beam of artificially-produced francium from the ISAC facility at TRIUMF. 相似文献

We have performed precision measurements in a magneto-optical trap of the 7P1/2 hyperfine structure of the isotopes 209-210Fr. The ratio of these hyperfine constants to the previously measured 7S1/2 ground state values reveals a significant hyperfine anomaly. This anomaly results from the different radial dependence of
the electron density in the two atomic levels. The measurements are sensitive to changes in the radial distribution of the
neutron magnetism.

The francium atom offers an excellent laboratory to study electron-nucleus interactions. As the heaviest alkali, its atomic
properties can be calculated with high precision, and laser trapping methods now allow precision optical spectroscopy of many
isotopes. Recent measurements of the 7P1/2 hyperfine structure, when coupled with previous measurements of the ground state hyperfine structure reveal a hyperfine anomaly.
The change in anomaly between an even-N isotope and an odd-N isotope is sensitive to the radial distribution of the neutron magnetization.
