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

Isotope shifts and hyperfine spectrum of singly ionized neodymium ion was measured by collinear fast-ion-beam laser spectroscopy. The hyperfine A constants and B constants are obtained for the (23230)^o_9/2 level and 4f⁴5d ⁶K_9/2 level, respectively. The optical isotope shifts between seven isotopes in the 580.56 nm of ^{142-145,146,148,150}Nd⁺ line are determined. The configuration admixtures for (23230)^o_9/2 level were quantitatively analysed to be 4f⁴6p, 4f³5d², and 4f³5d6p with mixing coefficients of 67%, 5%, and 28%, respectively.
