route, the production cross-sections of 52gMn via deuteronirradiation was scarcely reported. The TENDL-2014 could
not accurately predict the excitation function of thisradionuclide.

3Cross Section (mb)Nickel (Ni) has been given priority over several othermaterials in a recent IAEA Coordinated Research Project on
Nuclear Data Libraries for Advance Systems - Fusion
Devices. Ni also can be used as a target material for theproduction of radionuclides by accelerators leading to
medical and industrial applications. Co radionuclides suchas 55,56,57Co found potential applications in medicine andother basic research fields due to their suitable decay
characteristics 1). 55Co found important applications inlabelling bleomycin and in the studies of cerebral andcardiac problems via PET. 57Co plays a significant role as acalibration standard in Ȗ-ray spectrometry and single photon
emission computed tomography (SPECT) 2). A detailed
literature survey of experimental data via deuteron
bombardment of nickel show large discrepancies among theprevious data. More so, experimental data via the deuteron
bombardment process are relatively scarce, leading tofurther need of enriching the database. In this article, newexperimental cross-sections of several radionuclides werereported via deuteron irradiation of some stacked foils madefrom natural Ni. A well-established stacked foil activation
technique combined with Ȗ-ray spectrometry was employed
to determine the cross-sections of the natNi(d,x)55-58,60Co,57
Ni, 52g,54Mn, and 61Cu reactions for the deuteron energy
range of 24 MeV down to the respective thresholds 3).
Using a water-cooled target holder that served as a
Faraday cup, two stacks were irradiated for 2.00 h and 2.07
h, respectively, with a 24-MeV deuteron beam energy andabout 200 nA beam current from the AVF cyclotron ofRIKEN RI Beam Factory, Japan 3). The beam intensity wasdetermined from the activity of the Ti foil placed at thefront of the stacks, and considered as a constant to deducecross-sections for each foil in the stack. The natTi(d,x)48V
monitor reaction (ı = 217.54 mb at Ed = 23.88 MeV)
recommended by the IAEA 3) was adopted to evaluate thebeam intensity.
The production cross-sections of 55-58,60Co, 57Ni, 52g,54Mn,
and 61Cu radionuclides were reported in the tables andfigures in Ref. 3), together with extensive reviews ofEXFOR data base and also TENDL-2014. Owing to space,60m+g
Co and 52gMn are given
only excitation functions ofhere. Only two earlier studies reported the cross-sections of60
Co, and they are inconsistent with each other as shown inFig. 1. The prediction by the Talys code extracted fromTENDL-2014 database could not also give a good
approximate of the excitation function of 60Co. A separate
experiment based on the optimized experimental condition
for 60Co may be helpful to obtain a more reliable excitation
