Abstract

For the first time, in-gas-cell laser spectroscopy study of the Cu57,59,63,65 isotopes has been performed using the 244.164 nm optical transition from the atomic ground state of copper. The nuclear magnetic dipole moments for Cu57,59,65 relative to that of Cu63 have been extracted. The new value for Cu57 of μ(Cu57)=+2.582(7)μN is in strong disagreement with the previous literature value but in good agreement with recent theoretical and systematic predictions.

Lasers light up some magnetic moments

Published 31 August 2009

A laser spectroscopy technique that has helped resolve a puzzle about the structure of 57Cu could prove useful in studying other exotic, short-lived nuclei.
