Cluster structures of excited states in ${}^{14}$C

Abstract

Structures of excited states in ${}^{14}$C are investigated with a method of $\beta$-$\gamma$ constraint antisymmetrized molecular dynamics in combination with the generator coordinate method. Various excited states with the developed $3\alpha$-cluster core structures are suggested in positive- and negative-parity states. In the positive-parity states, triaxial deformed and linear-chain structures are found to construct excited bands. Interestingly, ${}^{10}$Be+$\alpha$ correlation is found in the cluster states above the ${}^{10}$Be+$\alpha$ threshold energy.
