Precision spectroscopy of Ba+ isotopes in a Paul trap — •Nivedya Valappol, Elwin Dijck, Amita Mohanty, Klaus Jungmann, Lorenz Willmann, and Aswin Hofsteenge — Van Swinderen Institute, University of Groningen, The Netherlands

We perform precision spectroscopy on Ba+ ions and precisely determine the 6s2S1/2 - 6p2P1/2, 6p2P1/2 - 5d2D3/2, 6s2S1/2 - 5d2D5/2 transition frequencies. We have achieved more than 100 times improved values using single trapped ion and frequency comb and I2 line locked laser system. We have reached 10−11 relative accuracy, where these values test precisely the atomic wave functions. This is important input for a measurement of atomic parity violation in the alkaline earth atoms.
