Abstract

The Kr isotopes are considered to be among the best cases for shape coexistence studies in the mass A ∼ 70 region. Our campaign to investigate in detail the development of the shape coexistence in the neutron deficient Kr isotopes was started with the stable nucleus ⁷⁸Kr. To obtain the information about the intrinsic shape, Coulomb excitation experiments were performed. A total of 26 matrix elements were determined for ⁷⁸Kr. Simple geometrical and algebraic models do not reproduce all details of the electromagnetic structure. A good interpretation of the complex structure of the nucleus with competing oblate and prolate shapes comes from a study within the complex EXCITED VAMPIR approximation using Hartree-Fock-Bogoliubov transformations with symmetry projection before variation. The measured matrix elements are compared with the predictions of this model.
