Angular correlations in muon capture including linear polarization of the de-excitation gamma-quanta

Angular correlations coefficients are calculated for the nuclear cascade process j0(mezoatom) μ-→j1γ→j2. When introducing explicitly a photon polarization density matrix, a new quantity is distinguished. It is the imaginary part of the muon capture partial amplitudes, providing another check of the T-invariance in the μ-capture. The new quantity could be measured only by means of the linear polarization of the emitted γ-quanta. (author)
