Recoil distance method lifetime measurement of the 2⁺₁ and implications for the structure of neutron-rich Sr isotopes

NUCLEAR REACTIONS ²⁷Al(⁹⁴Sr, ⁹⁴Sr'), (⁹⁴Sr, ²⁷Al')E=280 MeV; measured Eγ, Iγ, (²⁷Al)γ-coin, half-life of the first 2⁺ state in ⁹⁴Sr by recoil-distance method (RDM) using TIGRESS Integrated Plunger (TIP), and TIGRESS array for γ detection at TRIUMF-ISAC-II accelerator facility. Coulomb excitation. Geant4 simulations. ⁹⁴Sr; deduced level, B(E2) for the first 2⁺ state. Comparison with previous measurements, and with theoretical model calculations.
