Description
Recent theoretical studies indicate that triaxial deformation may occur in many nuclei including those having axially symmetric shapes in conventional view. I will present an overview of such a novel picture confirmed by the state-of-the-art large-scale shell-model (or CI) calculations. I will then talk about a possible experimental clarification for the case of 154Sm nucleus. This nucleus has been classified as a typical example of axially-symmetric prolate deformation, but it may be triaxially deformed with triaxial parameter gamma equal to about 4 degrees. As a direct test of this prediction, the electron inelastic scattering is expected to play a pioneering role. I will further report what is predicted for other nuclei, as well as the significance of this case in a broad view.
