Abstract

We consider parity nonconservation effect for the Mossbauer transitions in Fe57 and Sn119 nuclei. To simplify the calculations we use contact approximation for nucleon-nucleon weak interaction. A corresponding parity nonconserving effective Hamiltonian is presented. The result of the calculation of γ-quantum circular polarization degree P∼3×10−8 strongly contradicts the experimental value P∼10−3. One may consider this huge disagreement as an indication of the unknown nuclear phenomena which leads to the enhancement of parity nonconservation. We stress the importance of a new independent measurement of the effect.
