Nuclear charge distributions

A study of short-range correlation effects on nuclear spatial and momentum distribution

“…As anticipated in Sect. 2 the main peak of the function w,(x) remains at the same position while that of %(x) is shifted to greater values of x in accordance with (11).…”

“…5. Weighting functions w, (solid line) and wp (dashed line) for 4~ calculated by the single-particle potential method of Malaguti et al [10,11] at least for 1.5<x<2.5 fm, are closer to one another in the correlated case that in the single-particle model. This explains why the CFM contains some high-momentum components which are however weaker than those, induced by the Jastrow-type SRC, as shown in Fig.…”

“…kF being the Fermi momentum, while wo(x ) peaks at the value R A =(A/4)l/3ro (11) which is close to the nucleus radius.…”

“…In Sect. 3 this method is applied to the harmonic oscillator model of 4He and 160, with and without Jastrow correlations, and to the 4~ nucleus in the single-particle potential model [10,11]. Some comparisons are made with the CFM.…”

Short-range correlations and one-body properties of nuclei

“…1 or the first terms in (3.2) and (3.8), respectively). For nuclei with total momentum J= 0 (the case of the closed shell nuclei) the one-body density matrix has to be diagonalized within the { ~/'m } subspace of the complete space of the natural orbitals [26]. Moreover, the restriction to nuclei with closed major shells completely determine the angular part of the natural orbitals.…”
