Configuration-interaction calculation of hyperfine and $P, T$ -odd constants on ${}^{207}{Pb} O$ excited states for electron electric-dipole-moment experiments

We report first configuration interaction calculations of hyperfine constants

A_{‖}

and the effective electric field

W_{d}

acting on the electric-dipole moment of the electron, in two excited electronic states of

{}^{207}{Pb} O

. A combined scheme of correlation calculations is also developed and applied to studying the core properties. The obtained hyperfine constants,

A_{‖} = - 3826 MHz

for the

a (1)

state and

A_{‖} = 4887 MHz

for the

B (1)

state, are in very good agreement with the experimental data,

- 4113 MHz

and

5000 \pm 200 MHz

, respectively. We find

W_{d} = - ({6.1}_{- 0.6}^{+ 1.8}) \times 10^{24} Hz ∕ (e cm)

for

a (1)

, and

W_{d} = - (8.0 \pm 1.6) \times 10^{24} Hz ∕ (e cm)

for

B (1)
