E. Stachowska et al., HYPERFINE-STRUCTURE INVESTIGATION ON THE (3D(4))(3)G(4,5) LEVELS OF TI-47, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 27(4), 1993, pp. 303-306
Using two-step laser spectroscopy with the sideband technique the hype
rfine structure (hfs) splittings of the levels (3d4) 3G4,5 in Ti-47 ha
ve been measured. These are the first hfs measurements of the levels b
elonging to the 3d(N+2) configuration of the system (3d + 4s)N+2. The
experimental results indicate a strong increase of the core polarizati
on effect due to excitation of both 4s-electrons to the open 3d-shell.
