Abstract

The hyperfine structure (hfs) and gJ value of the metastable (5d96s2) D322 and of the (5d96s6p) F924 levels in Au197 have been measured by the atomic-beam magnetic-resonance method. The results for the hfs interaction constants, which have been corrected for second-order interactions with neighboring fine-structure levels, are A(D322)=199.8425(2) Mc/sec, B(D322)=-911.0766(5) Mc/sec, C(D322)=0.000212(14) Mc/sec, A(F924)=432.276(1) Mc/sec, B(F924)=-540.026(17) Mc/sec, and C(F924)=0.00326(10) Mc/sec. A detailed interpretation of these measurements together with those of Goodman and Childs on the (5d96s2) D522 level yields a value for the quadrupole moment of Q=0.594(10) b without the Sternheimer correction. We are not able to obtain a consistent value for the octupole moment. From the Zeeman effect of the hfs we find gJ(D322)=0.799(1) and gJ(F924)=1.334(2). © 1967 The American Physical Society.
