Abstract: (Elsevier)

A method of integral detection of γ quanta with subsequent resonance separation and storage of a periodic signal was used to measure the circular polarization of γ quanta in 181 Ta (a transition of 482 keV). The value of the polarization obtained is P γ = −(6 ± 1) × 10 −6 . This result agrees with the data obtained by the authors earlier, P γ < 2 × 10 −5 , and is at variance with the value reported by Boehm and Kankeleit, P γ = −(2 ± 0.4) × 10 −4 . The amplitude of the nucleon-nucleon weak interaction estimated from a comparison with experimental data on 175 Lu is F ≈ (2 ± 4) × 10 −7 .
