\begin{document}$ A\approx 60 $\end{document} mass region, we study the doublet bands built on the configuration \begin{document}$ \pi f_{7/2}^{-1} \otimes \nu g_{9/2}^{1} $\end{document} using the particle rotor model (PRM) with residual proton-neutron interactions \begin{document}$ V_{pn} $\end{document} for cobalt isotopes. The energy spectra \begin{document}$ E(I) $\end{document}, energy difference between the doublet bands \begin{document}$ \Delta E(I) $\end{document}, electromagnetic transition probabilities \begin{document}$ B(M1) $\end{document} and \begin{document}$ B(E2) $\end{document}, and the energy staggering \begin{document}$ S(I) $\end{document} of the doublet bands are calculated by varying the deformation parameters β and γ and moment of inertia \begin{document}$ \mathscr{J} $\end{document}. The PRM calculations show that the parameters for the ideal chirality of the configuration \begin{document}$ \pi f_{7/2}^{-1} \otimes \nu g_{9/2}^{1} $\end{document} are \begin{document}$ \beta=0.25 $\end{document}, \begin{document}$ \gamma=34^{\circ} $\end{document}, and \begin{document}$\mathscr{J}= $\end{document}\begin{document}$ 10\; \hbar^2/\rm MeV$\end{document}. Subsequently, PRM calculations adopting these parameters show that \begin{document}$ \Delta E(I) $\end{document} and \begin{document}$ S(I) $\end{document} are sensitive to the residual proton-neutron interactions \begin{document}$ V_{pn} $\end{document}. A weaker \begin{document}$ V_{pn} $\end{document} is more conducive to the existence of nuclear chirality. Finally, the evolution of the chirality with spin I is illustrated using the probability of the total angular momentum along the principal axes (K distribution) and the orientation with respect to the intrinsic frame \begin{document}$ \mathscr{P}(\theta,\varphi) $\end{document}."> Exploring chiral rotation in <i>A</i> ≈ 60 nuclei: Role of residual interactions -
