T. Maruyama et al., QUANTUM MOLECULAR-DYNAMICS APPROACH TO THE NUCLEAR-MATTER BELOW THE SATURATION DENSITY, Physical review. C. Nuclear physics, 57(2), 1998, pp. 655-665
Quantum molecular dynamics is applied to study the ground state proper
ties of nuclear matter at subsaturation densities. Clustering effects
are observed to soften the equation of state at these densities. The s
tructure of nuclear matter at subsaturation density shows some exotic
shapes with variation of the density.
