Coulomb excitation of radioactive Te-132,Te-134,Te-136 beams and the low B(E2) of Te-136

The B(E2;0(+)-->2(+)) values for the first 2(+) excited states of neutron-rich Te-132,Te-134,Te-136 have been measured using Coulomb excitation of radioactive ion beams. The B(E2) values obtained for Te-132,Te-134 are in excellent agreement with expectations based on the systematics of heavy stab...

Descripción
Sumario:The B(E2;0(+)-->2(+)) values for the first 2(+) excited states of neutron-rich Te-132,Te-134,Te-136 have been measured using Coulomb excitation of radioactive ion beams. The B(E2) values obtained for Te-132,Te-134 are in excellent agreement with expectations based on the systematics of heavy stable Te isotopes, while that for Te-136 is unexpectedly small. These results are discussed in terms of proton-neutron configuration mixing and shell-model calculations using realistic effective interactions.
