1 \times 10^{10}$ G. The mixing angle $\sin^22\theta_{13}$ is assumed to be 0.04, corresponding to the adiabatic MSW-H resonance. The effective squared masses are different between neutrinos and antineutrinos in a finite density. The relation of the effective squared masses is as follows: $\tilde{m}^2_{\bar{\nu}_1} \le \tilde{m}^2_{\nu_1}$, $\tilde{m}^2_{\nu_2} \le \tilde{m}^2_{\bar{\nu}_2}$, and $\tilde{m}^2_{\nu_3} \le \tilde{m}^2_{\bar{\nu}_3}$, independent of mass hierarchy and the equalities are satisfied in vacuum.

Figure 2 shows the density dependence of the effective squared masses in normal mass hierarchy. In the case of $Y_e = 0.49$, the dependence of the squared masses is well explained in [@af03]. We see five resonances, the MSW-H, L, and the RSF-H, L, and X. In the high density limit, $\nu_e$ and $\bar{\nu}_e$ correspond to $\bar{\nu}_2$ and $\nu_2$, respectively. At the same time, both $\nu_{\mu}$ and $\nu_{\tau}$ are the mixed states of $\nu_1$ and $\bar{\nu}_1$. Therefore, the conversion of $\bar{\nu}_e$ and $\nu_{\mu,\tau}$ occurs at the RSF-H resonance. The conversion of $\nu_e$ and $\bar{\nu}_{\mu,\tau}$ occurs at the RSF-X resonance.

In the case of the normal mass hierarchy and $Y_e = 0.51$, the dependence of the effective squared masses is different from the case of $Y_e = 0.49$. The effective squared mass of $\nu_e$ is the largest
