Reduced transition probabilities for the first 2$^+$ excited state in $^{46}$Cr, $^{50}$Fe, and $^{54}$Ni

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.
