Abstract
Activation cross sections of the ^{mathrm {nat}}hbox {Rb (d,xn)}^{87mathrm {m,85m,85g,83,82}}hbox {Sr}, ^{mathrm {nat}}hbox {Rb(d,x)}^{mathrm {86,84,83,82m}}hbox {Rb} and ^{mathrm {nat}}hbox {Rb(d,x)}^{85mathrm {m}}hbox {Kr} nuclear reactions have been measured for the first time through an activation method combining the stacked foil irradiation technique and gamma-ray spectrometry. The provided cross sections from the present investigation are all new, in such a way contribute to the completeness of the experimental database. The experimental cross sections were compared with the theoretical prediction in the TENDL-2019 TALYS based library and with our calculation using ALICE-D and EMPIRE-D model codes in order the improve their predictivity. Thick target production yields were calculated form the new cross sections for all investigated radioisotopes. Practical applications of the results are shortly discussed.

Summary
Unlike for proton induced reactions, the status (reliability and completeness) of the experimental data for deuteron induced reactions was rather poor, especially above 15–20 MeV. In this work we present the excitation functions for reactions on rubidium (stable isotopes 85Rb and 87Rb) leading to radionuclides of Sr, Rb and Kr. The measured excitation functions are compared with the results of three nuclear reaction model codes. The measured excitation functions are compared with the results of three nuclear reaction model codes These comparisons can show the present status of the predictivity of these codes and contribute to their development. The reliability of the presently used theoretical codes for deuteron induced reactions is low, compared to proton and alpha particle induced reactions, due to the modeling problems of the deuteron stripping and pickup. Integral physical yields at 22 MeV deuteron energy were reported by Dmitriev et al [1] for production of 84,86Rb and 85Sr
