Abstract: EC.00008 : Short-range correlations and momentum distributions in light nuclei
9:00 PM–9:15 PM
Since the precise solution can be obtained for a four-nucleon system, 4He, the system can be a testing ground of nuclear interactions and an ideal nucleus to study many-nucleon correlations. We perform an ab initio calculation for 4He using the explicitly correlated Gaussian expansion of the wave function  and discuss its correlated structure in the ground state as well as in excited four-nucleon states from various viewpoints. We extract density and momentum density distributions from highly correlated wave function and discuss a role of short-range two-body interaction . As a theoretical interest, we translate the short-range correlations in a language of the harmonic-oscillator wave function which is widely employed in shell model calculations . We discuss how the many-body correlations appear in the momentum distributions from the viewpoint of the effective nuclear interaction .
