Nuclear Alpha-Particle Condensates

Understand

The $\alpha$-particle condensate in nuclei is a novel state described by a product state of $\alpha$'s, all with their c.o.m.

• in the lowest 0S orbit.
• We demonstrate that a typical $\alpha$-particle condensate is the Hoyle state ($E_{x}=7.65$ MeV, $0^+_2$ state in $^{12}$C), which plays a crucial role for the synthesis of $^{12}$C in the universe.
• The influence of antisymmentrization in the Hoyle state on the bosonic character of the $\alpha$ particle is discussed in detail.
