First-excited state g factor of ¹³⁶Te by the recoil in vacuum method

NUCLEAR MOMENTS ¹³⁶Te; measured g factor of the first excited 2+ state by recoil-in-vacuum (RIV) technique following Coulomb excitation using 410-MeV ¹³⁶Xe beam and ⁵⁰Ti target at Holifield Radioactive Ion Beam Facility (HRIBF) at ORNL. The (particle)γ(θ) were measured using HPGe Clarion array for γ rays, a 2π CsI array for particle detection, and a Bragg-Curve gas detector. Comparison with Shell model calculations with interactions derived from the CD Bonn potential. Free-ion hyperfine interactions and methodology for ¹³⁶Te re-evaluated by calibration of RIV interaction through Coulomb excitation of stable Te isotopes on ⁵⁰Ti target. ¹²⁶Te; measured g factor of the first 2+ state.
