Abstract The fine structure (fs) splittings in the 1s2p 3 P J=1,2,0 multiplet of the helium-like7Li+ ion were measured with a laser spectrometer. The results with 3σ errors are: Δv 01 (3 P 0,F=3/2−3 P 1,F=5/2)=152081.6(2.0) MHz and Δv 02 (3 P 0,F=3/2−3 P 2,F=7/2)=82704.3(1.9) MHz. Combining the new precise fs measurements with earlier hyperfine structure (hfs) results from laser-microwave spectroscopy provided improved fs constants:D 1=−155709.0(2.1) MHz,D 2=−93049.2(2.0) MHz, and hfs constants:A c =3679.0(6) MHz,A 0=51.0(4) MHz, andA d =−11.3(1) MHz, thus allowing for a stringent test of available theoretical data. The spectroscopic method used in this work opens up the possibility of determining Li+, 23 S−23 P absolute transition frequencies with a precision of ∼2·10−9.
