Abstract

The asymmetry of even-even nuclei with 46≤ A ≤82 (22≤ Z ≤34) is studied by the sum-rule method applying recently introduced approximations. The uniquely high eccentricities of 72−76Ge and 74–78Se point at the most pronounced (effective) triaxiality of ground states emerging so far from the experimental data for 46≤ A ≤192.
