Container model for the ground and excited 0+ states in 12C

Container model for the ground and excited 0+ states in 12C

The original 3α THSR (Tohsaki-Horiuchi-Schuck-Röpke) wave function was extended to 2α+α THSR wave function for studying the rich cluster structures of 0+ states in 12C, which includes two size parameters and the 2α correlation was included in the container picture. It was found that the extended sin...

description The original 3α THSR (Tohsaki-Horiuchi-Schuck-Röpke) wave function was extended to 2α+α THSR wave function for studying the rich cluster structures of 0+ states in 12C, which includes two size parameters and the 2α correlation was included in the container picture. It was found that the extended single THSR wave functions give a very high-accuracy description of the ground state and also the excited 0+ states in 12C. By superposing the 2α+α THSR basis with the radius constraint method, we performed the GCM calculations for the 0+ states. The existence of the 03+ and 04+ states around 10 MeV were confirmed in this microscopical cluster model. The further study indicates the 03+ state can be considered as a breathing-like excited state of the Hoyle state.
