摘要：我们测量了B（E2;0+g.s.→ 2+1）值，以研究Z = 20-28区集体性的系统行为。本研究完成了直到Z = 28的Tz = ±1偶-偶对核的B（E2）值。质子和中子矩阵元的双比值，（|MN|/|MP|）/（N/Z），并与理论预测进行了比较。
Abstract.We measured B(E2;0+g.s. → 2+1) values for the proton-rich 46Cr, 50Fe, and 54Ni nuclides by intermediate-energy Coulomb excitation in order to study the systematic behavior of collectivity in the Z = 20-28 region. The present study completes the B(E2) values for the Tz = ±1 even-even pair nuclei up to Z = 28. The double ratios of proton and neutron matrix elements, (| Mn|/| Mp|)/(N/Z), have been extracted from the B(E2) values combining with the ones of their mirror nuclei, and compared with theoretical predictions.
