G. Basar et al., EXPERIMENTAL AND THEORETICAL-STUDY OF THE HYPERFINE-STRUCTURE IN THE (5D-I(6S)(9)6P CONFIGURATIONS OF PT), Zeitschrift fur Physik. D, Atoms, molecules and clusters, 36(1), 1996, pp. 35-39
The hyperfine structure of the odd configurations 5d(9)6p and 5d(8)6s6
p was studied with laser optogalvanic spectroscopy and high resolution
interferometry in a platinum hollow cathode. A parametric hyperfine s
tructure analysis for the configurations (5d + 6s)(9)6p with 10 excite
d odd-parity levels was performed for Pt-195. We obtained one-electron
hfs parameters, a(5d)(01) = 1160(320) MHz, a(6s)(10) = 35600(5300) MH
z and a(6p)(01) = 1300(780) MHz for the configuration 5d(8)6s6p. The c
orresponding [r(-3)](kskl)(nl) values are compared with those known fo
r other 5d-elements.
