Experimental determination of activation cross section of alpha-induced nuclear reactions on natPt

Alpha-particle induced nuclear reactions that result in the generation of several Hg (mass numbers 192, 193m, 193g, 195m, 195g, 197m, 197g, 199m) and Au (mass numbers 194, 195m, 195g, 196n, 196g, 198m, 198g, 199, 200m) radionuclides were investigated. The stacked-foil activation technique on natural platinum targets was used. Excitation functions are reported for Eα from threshold up to 37 MeV. Cross sections are reported for the first time for reactions of the type natPt(α,xn)∗Hg (x = 1–5) and natPd(α,pxn)∗Au (x = 1–5). The experimental results are compared with literature values and with model calculations performed with the ALICE-IPPE code. Use of the data for possible applications in comparison with our earlier results for proton and deuteron induced reactions is discussed.
