All materials on the earth are composed of atoms, and the atomic nucleus uniquely determines their properties. From previous studies, we know that the nucleus can be deformed depending on the nuclide and has various shapes such as lemon-shaped and pancake-shaped. These deformations are determined by the balance of the number of protons and neutrons that make up the nucleus, but the details of the mechanisms driving the deformations are not well understood. In this research, in order to directly observe this deformation mechanism, we will develop a new method to measure the shape with an accuracy of several fm using a crystal target.
