Doppler broadening as a probe of the chemical environment following oxygen-14 decay

A search for the Doppler broadening following the beta decay of oxygen-14 was conducted with high resolution gamma spectroscopy on the 2313 keV gamma ray. Such a broadening should signal the mass of the labeled molecule and the nature of the stopping medium. Oxygen-14 labeled H₂O, O₂ and CO₂ trapped on solid soda lime were investigated. No broadening was observed beyond the 1.65 keV instrumental resolution of the Ge detector, monitored by the unbroadened 2319 keV isomeric transition in ₉₀Nb decay.
