$\alpha$-Particle Condensation in Nuclear Systems

Abstract : The fameous Hoyle state ($O_2^+$ at 7.654 MeV in $^{12}$C) is identified as being an almost ideal condensate of three $\alpha$-particles, hold together only by the Coulomb barrier. It, therefore, has a $^8Be-\alpha$ structure of low density. Transition probability and inelastic form factor together with position and other physical quantities are correctly reproduced without any adjustable parameter from our two parameter wave function of α-particle condensate type. The possibility of the existence of $\alpha$-particle condensed states in heavier n$\alpha$ nuclei is also discussed.
