Abstract
We report on spectroscopic measurements on the 4 f 76s2 8S◦7/2 → 4 f 7(8S◦)6s6 p(1P◦) 8P9/2 transition in neutral europium-151 and europium-153 at 459.4 nm. The center of gravity frequencies for the 151 and 153 isotopes, reported for the first time in this paper, to our knowledge, were found to be 652,389,757.16(34) MHz and 652,386,593.2(5) MHz, respectively. The hyperfine coefficients for the 6s6 p(1P◦) 8P9/2 state were found to be A(151) = -228.84(2) MHz, B(151) = 226.9(5) MHz and A(153) = -101.87(6) MHz, B(153) = 575.4(1.5) MHz, which all agree with previously published results except for A(153), which shows a small discrepancy. The isotope shift is found to be 3163.8(6) MHz, which also has a discrepancy with previously published results.
