SPECTROSCOPIC DETERMINATION OF THE NUCLEAR MAGNETIC MOMENT OF PLUTONIUM 241

The study of the hyperfine structure of the I and lI spectra of Pu/sup 241/, carried out using a Fabry-Perot photoelectric spectrometer, shows that the nuclear magnetic mom t of Pu/sup 241/ is negative, with a value of --0.58 plus or minus 0.15 nuclear magnetons. (tr-auth)
