$\Delta {\mathit{\text{E}}}_{\text{b}-\text{m}}^{\ast }$ was determined for a range of values of R_p and R_b and plotted as an energy surface for these two parameters. C_m-i-0 = C_m-o-0 = −0.1 nm⁻¹ for a and b and C_m-i-0 = −0.15 nm⁻¹, C_m-o-0 = −0.05 nm⁻¹ for c. h = 1.7 nm for a and 2.1 nm for b and c. The symbol o marks the local energy minimum of 12.97 kT at R_p = 3.3 nm and R_b = 5.45 nm (a), 11.54 kT at R_p = 3.8 nm and R_b = 6.05 nm (b) and 55.7 kT at R_p = 2.9 nm and R_b = 5.3 nm (c)
