The new ansatz is based upon variationally distinguishing between the various components of the two-body Jastrow and operatorial correlations, which are operated upon by three-body and spin-orbit correlations. We obtain noticeable improvement in the quality of the wave function and lowering of the energies compared to earlier results. The new energies are -8.38(1), -28.07(1), and -29.90(1) MeV for 3H, 4He, and 6Li, respectively. Though, the present improved ansatz still fails to stabilize the 6Li nucleus against a breakup into an α particle and a deuteron by 390 KeV; nonetheless, it is an improvement over previous studies. 2014-02-24T10:40:48Z 2014-02-24T10:40:48Z 2012-09 Article Physical Review C - Nuclear Physics, vol. 86(3), 2012 0556-2813 http://journals.aps.org/prc/abstract/10.1103/PhysRevC.86.034323 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32136 en American Physical Society
