Seeking asymmetric rotors in mass region<i>A</i>∼100–110

Abstract

The staggering indices S(I, I−1, I−2) versus spin (I) graphs have been plotted using known experimental data along with empirical calculations of Varshney et al (2007 Phys. Scr. 75 451) in some nuclei of mass region A∼100–110. Most of the transional nuclei of Mo, Ru and Pd isotopes have been found to be triaxial. The known B(E2) values of these nuclei are also close to the triaxial rotor model predictions (Davydov A S and Filippov G F 1958 Nucl. Phys. 8 237).
