Fig. 5 The calculated dimensionless $R_{m}^{d}$ [(a), (b), (c)] and $ P_{\rm orb}^{d}$ [(d)] as functions of mass asymmetry at $R_{m}\le R_{t}=R_1+R_2$, $n=3$, and $l=2/3$. The plots (a) and (b) correspond to the system with the parallel and antiparallel orbital and spin angular momenta, respectively. In the plot (c), the cases of antiparallel spins with $L_1=J_{\rm tot}+S_1-S_2$ (dashed line) and $L_2=J_{\rm tot}-S_1+S_2$ (solid line) are presented. Note that the value of $ P_{\rm orb}^{d}$ does not depend on the orientations of orbital momentum and spins.
