Realistic Momentum Distributions of the Particle

Abstract
We present various types of momentum distributions of the α particle using ATMS wave function generated with the Reid soft core V 8 model potential. Those are the momentum distributions of the single-nucleon, two-nucleon-cluster relative motion, two-nucleon-cluster center of mass, triton-proton relative motion and deuteron-deuteron relative motion. These momentum distributions are well represented as a sum of Gaussian functions. With these Gaussian expansions, the realistic momentum distributions of the α particle would become accessible to everyone.
