the resonance. MSW-L resonance may convert $\nu_1$ and $\nu_2$. However, this resonance is adiabatic in this case. In vacuum, $\nu_1$ is the mixed state of 70 % of $\nu_e$ and 30 % of $\nu_{\mu,\tau}$. The mass eigenstate $\bar{\nu}_1$ is the mixed state of 70 % of $\bar{\nu}_e$ and 30 % of $\bar{\nu}_{\mu,\tau}$.

Second, Fig. 5 shows the conversion probabilities from $\nu_e$ \[5(a)\] and $\bar{\nu}_{\mu,\tau}$ \[5(b)\] in the case of the normal mass hierarchy and $Y_e = 0.51$ in the inner region. We see that the conversion between $\nu_e$ and $\bar{\nu}_{\mu,\tau}$ occurs at RSF-H resonance. The conversions at MSW-H and MSW-L resonances are also shown. However, no flavor conversion occurs at RSF-L resonance. In this case, all $\nu_e$ corresponds to $\bar{\nu}_3$ at the high density limit. When $Y_e$ changes from $Y_e > 0.5$ to $Y_e < 0.5$, no conversion of mass eigenstates occurs for $\bar{\nu}_3$. In the density region lower than MSW-H resonance, $\bar{\nu}_3$ corresponds to $\bar{\nu}_{\mu,\tau}$ and a small fraction of $\bar{\nu}_e$. Thus, $\nu_e$ changes to $\bar{\nu}_{\mu,\tau}$. On the other hand, $\bar{\nu}_{\mu,\tau}$ are the mixed states of $\bar{\nu}_2$ and $\nu_3$. The conversion between $\bar{\nu}_2$ and $\nu_3$ occurs at the location where the $Y_e$ changes. Then the two eigenstates convert again
