Microscopic Correlations in Nuclear Structure Calculations

We present the structure of ⁶Li and ¹⁸O calculated with the use of a dynamic correlation model. In our model, the nucleon-nucleon correlations are built into a set of nonlinear equations of motion, which we solve self-consistently to obtain the eigenstates of the nucleons that are dressed by their interactions with the nuclear medium. We have found that the solution does not depend on the original choice of the two-body matrix elements. The inputs to solve the dynamical eigenvalue-equations are the n-body matrix elements. We have developed a cluster factorization method to relate the n-body matrix elements to the (n-1)-body matrix elements by recursion relations. Hence all the needed n-body matrix elements can be built up from the basic 2-body matrix elements.
