Fig. 5: Split heatmap for contour plots of overlap.
The overlap \(| \langle {\Phi }^{{0}^{+}}({\beta }_{0})| {\Psi }_{{{{{{{{\rm{gcm}}}}}}}}}^{{0}_{\lambda }^{+}}\rangle |\) between the two-β GCM THSR wave functions and the single one-β THSR wave function for \({0}_{\lambda }^{+}\) states of 20Ne are calculated. The \({0}_{\lambda }^{+}\) states are labeled in the vertical axis. The β0 represents the size variable in the THSR wave function \({\Phi }^{{0}^{+}}({\beta }_{0})\). For the obtained 0+ states, the \({0}_{{{{{{{{\rm{I}}}}}}}}}^{+}\) and \({0}_{{{{{{{{\rm{II}}}}}}}}}^{+}\) states are corresponding the \({0}_{17}^{+}\) and \({0}_{19}^{+}\) states, respectively. Between the \({0}_{14}^{+}\) and \({0}_{15}^{+}\) states in the vertical axis, the short dashed line represents the 5α threshold.
