The E-gamma over spin (E-GOS) ratio, defined as \(R_{\mathrm {E-GOS}}(I)=E_{\gamma }(I\rightarrow I-2)/I\) , serves as a powerful tool in examining the transitions between vibrational and rotational structures. The mass region \(100 \le A \le 112\) has been recognised as a region of interest for such transitions, especially from \(\gamma \) -soft/vibrational to rotational structures. However, recent studies of nuclei, such as \(^{104}\) Pd and \(^{106,108,110}\) Cd, have revealed an exotic interesting phenomenon: a transition from \(\gamma \) -soft/vibrational to antimagnetic rotational behaviour along the yrast line. To explore this transition in a systematic manner, we have calculated two quantities: the average of the E-GOS ratio ( \({\overline{R}}_{\mathrm{E-GOS}}\) ) and the gradient of the E-GOS ratio ( \(g=\frac{\triangle R_{\mathrm{E-GOS}}}{\triangle I}\) ) at the band-head for both \(\gamma \) -soft/vibrational and antimagnetic rotational modes within a specific spin range.
