Abstract
Precise estimation of the rare direct 3α decay of the Hoyle state of 12C has been made to unveil its unusual α-cluster configurations ranging from linear 3α chain structure to diffuse Bose gas as well as Bose Einstein condensate. The present new high precision, nearly zero background experimental study with 1.6×105 Hoyle events has converged on the upper limit for direct decay at ∼0.019% with 95% confidence limit, which is more than a factor of 2 lower than the limit obtained in the previous studies.

Elements heavier than 4He have been produced in stars through stellar nucleosynthesis process, which starts from hydrogen burning process leading to the formation of 4He by fusion of four 1H nuclei; subsequently, other heavier elements are synthesised in steps [1]
