Measuring isospin mixing in Ar-36 using a polarized, neutral atom trap Conference Paper uri icon

abstract

  • Magneto-optical traps provide a cold, compact cloud of radioactive atoms and therefore are an ideal source for use in precision nuclear 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=2+ excited states of 36Ar with the lowest 2+, T=1 isobaric analog state. The spin-polarized 36K + 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. 2003 Elsevier Science B.V. All rights reserved.
