Abstract: | 21Na (T 1/2=23 sec) and37K(T 1/2=1.25 sec) have been produced in gas targets by (d, n) reactions and polarized by means of optical pumping or spin exchange scattering with optically pumped87Rb. An asymmetry up to 3% in theΒ-decay of the polarized nuclei was found, which served to detect rf transitions between hfs levels of the atomic ground states of21Na and37K.δF=0 andδF=1 resonances have been recorded, yielding spin, hfs separation and magnetic moment, especiallyI(37K)=3/2,δW(37K)=240.266 (3) Mc/sec andΜ I(37K)=0.02033(6) nm (diamagnetically corrected). For21Na earlier rf-spectroscopic data have been confirmed. |
