The nucleus 150 Nd was Coulomb excited using 14 N , 58 Ni and 92 Mo beams. The overall result of the experiments performed consists of 780 measured gamma yields, which combined with available spectroscopic data gave about 800 data points to overdetermine the set of matrix elements needed to describe the observed processes. A number of E1, E2 and E3 matrix elements coupling the low-lying states has been determined in a model-independent way. In addition, an influence of E4 moments, competing with double E2 excitations, was tested with the low energy 14 N beam. Possible interpretations of the unusual electromagnetic structure found experimentally may pose the challenge to the theorists.
