摘要: Abstract We derive a theoretical method for calculating the averages (over J and T) of matrix elements nuclear effective interaction, in any order linked cluster expansion. apply this to calculate all terms through fourth G-matrix, mass-6 mass-18 nuclei. find that are as large second third order. This behavior is associated with small number terms, which suggests partial summation improving series. The relation other work discussed.
