Abstract

The emergence of nuclear collectivity near doubly-magic ¹³²Sn was explored along the stable, eveneven ^124−130Te isotopes. Preliminary measurements of the B(E2; 4_1⁺ → 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 ⁵⁸Ni beams. A comparison of transition strengths obtained is made to large-scale shell-model calculations with successes and limitations discussed.
