| Abstract: | The moleculelike structure of the C isotopes (A=12, 14, 16) is investigated using a microscopic α+α+α+n+n+ … model. The valence neutrons are classified based on the molecular-orbit model, and both π orbit and σ orbit are introduced around three α clusters. The valence neutrons which occupy the π orbit increase the binding energy and stabilize the linear chain of 3α against the breathinglike breakup. However, 14C with the π orbit does not show a clear energy minimum against the bendinglike path. The combination of the valence neutrons in the π and σ orbits is promising to stabilize the linear-chain state against the breathing and bending modes, and it is found that the excited states of 16C with the (3/2π-)2(1/2σ-)2 configuration for the four valence neutrons is one of the most promising candidates for such a structure. |
