Experimental Studies on Electronic Configuration Mixing for the Even-Parity Levels of Gd I Using Isotope Shifts Recorded in the Visible Region with FTS
Figure 1
A high resolution spectrum in the region of 25575–25875 cm−1, recorded on FTS using liquid nitrogen cooled HCL containing highly enriched Gd-156 and Gd-160 isotopes (in 7 : 10 ratio) in the oxide form. Inset-expanded region showing IS −0.131 cm−1 in the spectral line at 390.270 nm of Gd I.
