Cluster structures and monopole transitions of 14C
Abstract
Cluster structures of 14C were investigated with a method of antisymmetrized molecular dynamics (AMD) combined with a 3α+nn cluster model while focusing on the monopole excitations and linear-chain 3α band. Variation after parity and angular momentum projections was performed in the AMD framework, and the generator coordinate method was applied to take into account various 3α+nn cluster configurations. Energy spectra and monopole and E2 transition strengths of 0+, 2+, and 4+ states were calculated to assign band structures. The 0+3 state with remarkable monopole transition was obtained as a vibrational mode of the triangle 3α configuration. In addition, the linear-chain 3α band from the band-head 0+4 state was obtained. 10Be+α decay widths of 0+, 2+, and 4+ states were evaluated. α inelastic scattering off 14C was also investigated by the microscopic coupled-channel calculation with the g-matrix folding model to propose possible observation of the 0+3 state via α scattering experiments.
