Selective decay from a candidate of the σ-bond linear-chain state in ¹⁴C

NUCLEAR REACTIONS ⁹Be(⁹Be, α¹⁰Be)He, E=45 MeV; measured particle spectra at HI-13 tandem accelerator of CIAE-Beijing facility. ¹⁴C; deduced level energies from reconstruction of forward moving ¹⁰Be+α fragments, resonances, decays to α cluster and ¹⁰Be in its ground state, first 2+, and about 6-MeV state, relative decay strength, indication of a σ-bond linear chain structure in ¹⁴C. Comparison with predictions of improved antisymmetrized molecular dynamics (AMD) theory.
