Magnetic dipole moment of 57,59Cu measured by in-gas-cell laser spectroscopy

TL;DR

This study used in-gas-cell laser spectroscopy to measure the magnetic dipole moments of copper isotopes 57, 59, 63, and 65, providing new data that challenges previous measurements and aligns with recent theories.

Contribution

First-time measurement of copper isotopes' magnetic dipole moments using in-gas-cell laser spectroscopy with a specific optical transition.

Findings

New value for 57Cu magnetic dipole moment significantly differs from previous data.

Results agree with recent theoretical and systematic predictions.

Demonstrates the effectiveness of in-gas-cell laser spectroscopy for nuclear property measurements.

Abstract

In-gas-cell laser spectroscopy study of the 57,59,63,65Cu isotopes has been performed for the first time using the 244.164 nm optical transition from the atomic ground state of copper. The nuclear magnetic dipole moments for 57,59,65Cu relative to that of 63Cu have been extracted. The new value for 57Cu of mu(57Cu) = +2.582(7)mu_N is in strong disagreement with the previous literature value but in good agreement with recent theoretical and systematic predictions.
