推导出一种有效的相互作用，以便在完整的基础上使用。从实际的g矩阵相互作用出发，通过拟合质量范围47 ~ 66的699个能量数据，确定了195个二体矩阵元素和4个单粒子能量。推导出的相互作用成功地描述了pf壳层核的各种结构。作为例子，给出了Ca、Ti、Cr、Fe和Ni同位素链中前2（+）态的能量系统，以及Ni-56、Ni-57和Ni-58的能级。一个新的神奇数字34出现了。
An effective interaction is derived for use in the full pf basis. Starting from a realistic G-matrix interaction, 195 two-body matrix elements and four single-particle energies are determined by fitting to 699 energy data in the mass range 47-66. The derived interaction successfully describes various structures of pf-shell nuclei. As examples, systematics of the energies of the first 2(+) states in the Ca, Ti, Cr, Fe, and Ni isotope chains and energy levels of Ni-56,Ni-57,Ni-58 are presented. The appearance of a new magic number 34 is seen.
