Abstract

Magneto-optical traps provide a cold, compact cloud of radioactive atoms and therefore are an ideal source for use in precision nuclear β decay studies. Optical pumping techniques can add a new dimension to such experiments by efficiently polarizing these samples to ≳99%. TRIUMF's experiment E925 is utilizing these techniques to prepare to measure the isospin mixing between the first two I^π=2⁺ excited states of ³⁶Ar with the lowest 2⁺, T=1 isobaric analog state. The spin-polarized ³⁶K β⁺ decay observables will be measured using TRIUMF's neutral atom trap at ISAC, TRIUMF's isotope separator and accelerator facility. The main purpose is to test isospin mixing models in the s,d-shell needed for determination of the superallowed Fermi strength in 0⁺→0⁺ decays.
