Description

Isotopically enriched xenon-130 was irradiated in a high-purity quartz ampule to produce xenon-131 and prompt gammas. Of the previously known 13 prompt gammas [1], 12 were measured with 85 newly observed gammas, whose energy distribution was in qualitative agreement with Monte-Carlo nuclear simulations [2]. Using the coincidences of the gammas, 21 new energy levels of the xenon-131 nucleus were measured up to 6.604 MeV. From the decay patterns, the parity of most new states was determined.
