Abstract.
A neutron number dependence of the E1 0+ 1 → 1- 1 reduced transition probability in spherical even-even nuclei is analysed within the Q-phonon approach in the fermionic space to describe the structure of collective states. Microscopic calculations of the E1 0+ 1 → 1- 1 transition matrix elements are carried out for the Xe isotopes based on the RPA for the ground-state wave function. A satisfactory description of the experimental data is obtained.
