186gRe is a β-/γ emitter of great interest for nuclear medicine. It has shown successful results on bone metastases palliation and has similar chemical properties as 99mTc, the most commonly used imaging agent. 186gRe is routinely produced using rhenium target in nuclear reactor. Higher specific activity could be obtained using accelerators. In this paper, production cross section values are presented for the natW (d, x)186gRe reaction up to 34 MeV, using the stacked-foils method and gamma spectrometry. From this data set, the thick target production yield of 186gRe is determined and compared with the validated values of the IAEA and also with the proton route. The production cross sections of the natW(d, x)183,182g,184m,184g,181Re and natW(d, x)187W reactions have also been determined. A good agreement is found with the literature. Our data are compared with the version 1.6 (December 2013) of the TALYS code which shows discrepancies both on the shape and on the amplitude for these deuteron induced reactions.
