Emerging nuclear collectivity in ${}^{124-130}$Te

Abstract

The emergence of nuclear collectivity near doubly-magic ${}^{132}$Sn was explored along the stable, even-even ${}^{124-130}$Te isotopes. Preliminary measurements of the $B(E2;4_1^{+}\to 2_1^{+})$ transition strengths are reported from Coulomb excitation experiments primarily aimed at measuring the $g$ factors of the $4_1^{+}$ states. Isotopically enriched Te targets were excited by 198-205 MeV ${}^{58}$Ni beams. A comparison of transition strengths obtained is made to large-scale shell-model calculations with successes and limitations discussed.
