Opposite deformations between protons and neutrons in proton-rich C isotopes

Abstract

Structures of C isotopes from the proton drip line to the neutron drip line are investigated in the framework of the antisymmetrized molecular dynamics (AMD). In particular, opposite deformations between protons and neutrons near the proton drip line are discussed in detail. We make certain of this new phenomenon suggested in the AMD results by analyzing the ratios of electric moments or transitions $[Q$ or $B\left(E2\mathrm{}\right)\mathrm{}$] in ${}^{10}$C and ${}^{11}$C to those in the mirror nuclei ${}^{10}$Be and ${}^{11}$B.
