Abstract
Using 4 mg of radiogenic Os187 the hyperfine structure of this isotope has been investigated with a recording Fabry-Perot interferometer. From the measurement of intensities and distances of the hyperfine-structure components in three fine-structure lines the spin and the magnetic moment of the Os187 nucleus have been determined to beI=1/2 andμ I =+(0,0652±0,0011) n.m.
In three fine-structure lines the isotopic shift has been measured and the relative isotopic shift of Os187 has been found to be\(\frac{{\Delta v(Os^{192} - Os^{187} )}}{{\Delta v(Os^{192} - Os^{190} )}} = 3,09 \pm 0,03\).
The two classifications of the fine-structure line λ 4261 Å have been verified by observing both transitions in Os187.
