Mass spectrometry was applied to the measurement of production cross section for the nuclear reaction <SUP>52</SUP>Cr(d, n)<SUP>53</SUP>Mn. Enriched <SUP>52</SUP>Cr metal target of about 60 mg/cm<SUP>2</SUP> 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 <SUP>53</SUP>Mn/ <SUP>55</SUP>ccMn was measured by mass spectrometry and the amount of <SUP>55</SUP>Mn was determined by neutron activation analysis.The ratio was up to2×10<SUP>-2</SUP>.The activity due to byproduct <SUP>54</SUP>Mn was about 5000 times higher than that of <SUP>53</SUP>Mn and it was attributed to <SUP>53</SUP>Cr impurity occurred at a level of 0.1% in the target through <SUP>53</SUP>Cr(d, n)<SUP>54</SUP>Mn. The activities of <SUP>53</SUP>Mn 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.
