壳模型有效相互作用GXPF 1的描述不稳定的pf壳核进行了测试。GXPF 1成功地描述了Ca、Ti和Cr同位素的N = 32壳层能隙，而Ti-56的E-x（2（1）（+））预测值与最近的实验数据有偏差，特别是在T = I时，需要对哈密顿量进行修正。与p（1/2）和f（5/2）轨道相关的矩阵元素。修改后的相互作用同时提供了所有这些同位素链的改进的描述。
The shell-model effective interaction GXPF1 is tested for the description of unstable pf-shell nuclei. The GXPF1 successfully describes the N = 32 shell gap in Ca, Ti and Cr isotopes, while the deviation of predicted E-x(2(1)(+)) in Ti-56 from the recent experimental data requires the modification of the Hamiltonian especially in the T = I. matrix elements related to the p(1/2) and f(5/2) orbits. The modified interaction gives improved description simultaneously for all these isotope chains.
