Evidence of the negative-parity linear-chain states in <sup>16</sup>C*
Abstract A new inelastic excitation and cluster-decay experiment was conducted to investigate the negative-parity linear-chain structure in 16 C. The helium and beryllium isotopes emitted from the highly excited states of 16 C and the recoil target deuteron were detected in coincidence. The 16 C excitation-energy spectra associated with different decay paths were reconstructed using the invariant mass method. Owing to the newly reconfigured detector setup, the detection acceptance was extended to a higher excitation-energy range, allowing a number of new resonant states to be observed beyond the previously reported -bond positive-parity linear-chain band. Based on comparison with the AMD calculations for both resonance energies and relative decay widths, these newly observed states can be tentatively assigned as the , , and members of the negative-parity linear-chain molecular rotational band. More experimental studies are expected to directly measure the spins of these states.
