Theranostic Hg-197m,Hg-g of high specific activity may be produced by proton or deuteron activation of gold. The particle choice affects the isomeric ratio. In order to compare both projectiles, we re-measured cross-sections of the nuclear reactions Au-197(d,x) Hg-197m, Hg-197g, Au-198m, Au-198g, Au-196m2, Au196m1+g in the energy range of 8.3-19.7 MeV having employed usual stacked-foil method. The obtained values were compared with previously measured data and with prediction of the TALYS nuclear reaction model code adopted from the TENDL-2017 library. Experimental data were used for calculation of the thick target yields. The yields for the isomeric pair Hg-197m,Hg-g were confronted with those for recently re-measured proton-induced reactions. We also provide a new data set for the reaction Cu-nat(d,x)Zn-63.
