Investigation of the near-threshold cluster resonance in ¹⁴C

【摘要】 An experiment for p(¹⁴C,¹⁴C^*→¹⁰Be+α)p inelastic excitation and decay was performed in inverse kinematics at a beam energy of 25.3 Me V/u.A series of¹⁴C excited states,including a new one at 18.3（1）Me V,were observed which decay to various states of the final nucleus of¹⁰Be.A specially designed telescope system,installed around zero degrees,played an essential role in detecting the resonant states near theα-separation threshold.A state at 14.1（1）Me V is clearly identified,being consistent with the predicted band-head of the molecular rotational band characterized by theπ-bond linear chain configuration.Further clarification of the properties of this exotic state is suggested by using appropriate reaction tools.更多还原
