Analysis of E1-transitions of odd-neutron nuclei of rare-earth elements. Effect of pairing correlations and state Coriolis mixing on E1-transitions in isotones with N=99-103

Analysis of E1-transitions (ΔK=1) of the 5/2-(512)↔7/2+(633)type, which are observed in odd-neutron nuclei of rare earth elements 165Dy, 167,169Er, 169,171,173Yb, 173,175Hf, 173,175W is carried out in this paper. Comparison of the experimental values of probabilities of this type E1-transitions shows considerable fluctuations of their values. The values of experimental and theoretical (at different approximations) probabilities given for E1-transitions of the type investigated are presented in tables. Analysis carried out for probabilities of E1-transitions of the type investigated showed that, besides including pairing interaction, which plays in this case an important role, consequently calculation in the framework of the non-adiabatic rotational model taking into account state Coriolis mixing is necessary
