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 cal
culated. Our result for the P-odd amplitude of the interaction with th
e weak charge of the nucleus is (70 +/- 40)(-i) Ha. The P,T-odd amplit
ude caused by the electric dipole moment of the electron d(e) is (1.2
+/- 0.5) x 10(23) Hz/(e cm). We also calculated g factors and hyperfin
e constants A and B for several levels. These results are in good agre
ement with experiment. The calculated lifetime of 6 mu sec for the pos
itive parity level is reasonably close to 8 mu sec measured by D. Budk
er et al. [Phys. Rev. Lett. 70, 3019 (1993)].
