• 論文の詳細を見る

• Dysprosium in terbium oxide powder was determined by a simple method involving 1 min. irradiation with pile neutrons of 3×10<SUP>11</SUP>neutrons per cm<SUP>2</SUP>/sec. and repeated γ-ray spectrometry using a 2 in. thick sodium-iodide crystal attached to a 256-channel pulse-height analyzer. Both interferences and the self-shielding effect were negligible. The coefficient of variation of single analyses was 5.2% for a 24 mg. sample of 48 p. p. m. dysprosium content.
