CALCULATION OF THE WEAK-INTERACTIONS IN DYSPROSIUM

P-odd and P,T-odd transition amplitudes for the two almost degenerate levels of opposite parity with J=10 and E=19 797.96 cm-1 are calculated. Our result for the P-odd amplitude of the interaction with the weak charge of the nucleus is (7040)(-i) Hz. The P,T-odd amplitude caused by the electric dipole moment of the electron de is (1.20.5)×1023 Hz/(e cm). We also calculated g factors and hyperfine constants A and B for several levels. These results are in good agreement with experiment. The calculated lifetime of 6 sec for the positive parity level is reasonably close to 8 sec measured by D. Budker et al. [Phys. Rev. Lett. 70, 3019 (1993)]. © 1994 The American Physical Society.
