Measurement of hyperfine structure and isotope shifts in the 580.56nm line of 142−145,146,148,150 Nd +

Abstract

Isotope shifts and hyperfine spectrum of singly ionized neodymium ion was measured by collinear fast-ion-beam laser spectroscopy. The hyperfineA constants and B constants are obtained for the (23230)o9/2 level and 4f45d 6K9/2 level, respectively. The optical isotope shifts between seven isotopes in the 580.56 nm of 142−145,146,148,150Nd+ line are determined. The configuration admixtures for (23230)o9/2 level were quantitatively analysed to be 4f46p, 4f35d2 and 4f35d6p with mixing coefficients of 67%, 5% and 28%, respectively.
