对富中子同位素Cr进行了中能库仑激发测量。首次测定了Cr的电四极激发强度（2; 0）。结果量化的趋势增加四极集体在铬同位素接近中子数。结果面临着大规模的壳模型计算在theshell使用的国家的最先进的Linguistic有效相互作用。不同的有效电荷集进行了讨论，提供了一个改进的和强大的描述thevalues的富中子的Fe和Cr同位素在这个地区的快速壳演化。中子和质子的过渡矩阵元素的比例，提出作为一个有效的工具来区分各种选择的有效电荷。
Intermediate-energy Coulomb excitation measurements were performed on the neutron-rich isotopesCr. The electric quadrupole excitation strengths,(2; 0), ofCr are determined for the first time. The results quantify the trend of increasing quadrupole collectivity in the Cr isotopes approaching neutron number. The results are confronted with large-scale shell-model calculations in theshell using the state-of-the-art LNPS effective interaction. Different sets of effective charges are discussed that provide an improved and robust description of thevalues of the neutron-rich Fe and Cr isotopes in this region of rapid shell evolution. The ratio of the neutron and proton transition matrix elements,, is proposed as an effective tool to discriminate between the various choices of effective charges.
