“…It is believed that the occurrence of this peculiar state is not just a lucky coincidence 20 , 26 . This triggered the intense search for the N α condensate in atomic nuclei, both experimentally 27 – 29 and theoretically 30 . Theoretical studies 31 – 33 show that the state of 16 O is a strong candidate for 4 α condensate and great experimental efforts are being made using sequential decay measurement to confirm it.…”

The formed 4He (α) clusters consisting of two neutrons and two protons can be a building block in light nuclear systems. Intriguingly, these alpha clusters could potentially form alpha condensate states within the nuclear system. The Hoyle state at 7.65 MeV in 12C, which plays an essential role in stellar nucleosynthesis, is now considered to be a phase transition, namely the 3α Bose-Einstein condensate. Confirming the existence of Hoyle-analog states in Nα nuclei (N > 3) remains a major challenge. Here we show microscopic five-body calculations for the 20Ne nucleus. We find that one excited 0+ state has a distinct gas-like characteristic and represents the condensate state. Identifying the 5α condensate state is an important step in establishing the concept of α condensation in nuclear fermion systems.
