Core polarization charge forE6transition

Core polarization charge for $E6\mathrm{}$ transition in the vicinity of ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ is calculated by the Bohr-Mottelson particle-vibration coupling model. A negative $E6\mathrm{}$ proton polarization charge $\delta e_p^{L=6\mathrm{}}=-0.06\mathrm{}$ is obtained because the isovector coupling constant is strongly repulsive and the lowest isoscalar particle-hole $6^{+}$ state is not collective. Comparison between the schematic interaction and other effective forces is discussed in calculations of core polarization charges of electric transitions.
