Sažetak
The so-called Hoyle state in 12C (7.654 MeV, 0+) is an excited state of 12C characterized by a well-pronounced 3α cluster nature. Many possible cluster configurations, such as a linear-chain arrangement of 3α particles, bentarm, triangular or gas-like structures were theoretically conjectured within the previous decades, but, also due to the existence of ambiguities in experimental data, it is still impossible to draw a firm conclusion. Its direct α-decay partial width is accurately predicted by models but requires better experimental constraints. We performed a high-precision and high-selectivity investigation of its α-decay by using the 14N(d, α2)12C- reaction at 10.5 MeV incident energy with the aim of distinguishing between sequential and direct decay patterns. We are able to significantly improve the state of the art upper limit for direct 3α decays by placing the new limit at 0.043%. Such a low limit allows to give fundamental constraints to theoretical models attempting to describe the structure of the Hoyle state.
