文摘

The nucleonic   matter operator-dependent correlation functions in the coupled channels, i.e. the S13–D13 and the P23–F23 channels, for the Av18Av18 interaction, are obtained by the use of lowest order constrained variational (LOCV  ) method. While, in the S13–D13 channel, only, the tensor-dependent correlation function is considered; in the P23–F23 channel, the spin-obit-dependent correlation function is included as well. It is demonstrated that the S13–D13 channel tensor-dependent correlation function is dominant in the symmetric nuclear matter (SNM  ). In other words, the P23–F23 channel tensor- and spin–orbit-dependent correlation functions do not play any significant role in the SNM. Whereas, it is shown that the spin–orbit-dependent correlation function notably declines the LOCV pure neutron matter (PNM) energy, especially at high densities. Finally, it should be declared that, generally, the spin–orbit-dependent correlation functions are short-range in comparison with those of tensor-dependent.
