Experimental Studies on Electronic Configuration Mixing for the Even-Parity Levels of Gd I Using Isotope Shifts Recorded in the Visible Region with FTS
Table 3
Odd-parity energy levels (cm−1), their configurations, term, and values have been taken from [1]. LIS (cm−1) have been referred from [6–9].
$We have marginally revised the LIS (cm−1) values of these levels on the basis of present IS data obtained using FTS combining with the data available in the literature mostly studied by laser spectroscopy.
