Abstract

Mass spectrometry was applied to the measurement of production cross section for the nuclear reaction ⁵²Cr(d, n)⁵³Mn. Enriched ⁵²Cr metal target of about 60 mg/cm² was prepared on a copper plate holder by electrodeposition and was bombarded with deuterons in a cyclotron. Manganese was extracted and purified without using carrier from bombarded targets by anionuexchange and solvent extraction. The isotopic ratio ⁵³Mn/ ⁵⁵ccMn was measured by mass spectrometry and the amount of ⁵⁵Mn was determined by neutron activation analysis.The ratio was up to2×10^-2.The activity due to byproduct ⁵⁴Mn was about 5000 times higher than that of ⁵³Mn and it was attributed to ⁵³Cr impurity occurred at a level of 0.1% in the target through ⁵³Cr(d, n)⁵⁴Mn. The activities of ⁵³Mn obtained were 5-80dpm by60-160 millicoulombs of 8.3-20.0 MeV, deuterons. The average cross sections were estimated in each experiment and were compared with those of the analogous nuclear reactions.
