Detailed shape measurements of single-component crystals containing about 305(10) ⁴⁰Ca⁺ ions in a group of different U _end values. (a) Relation between the sizes of the principal axes 2 R and 2 L of the ellipsoidal Coulomb crystals and U _end. (b) The volumes and number of ions in the ellipsoidal Coulomb crystals keep nearly unvaried with U _end.
