Target foil stacks of terbium were bombarded with -particles of incident energies 55 MeV. Excitation functions for the /,xn/ x=2–5 reactions were determined. On the basis of the cross sections, the thick target yields of/163–x/Ho /x=2.5/ have been evaluated. Activation and stacked-foil techniques were applied.

The stacked foil technique was used in combination with -ray spectroscopy to obtain excitation functions for the production of different nuclei using natural vanadium as target and 85 MeV -particles and 46.5 MeV deuterons as projectiles. The data are compared with theoretical predictions provided by an equilibrium and pre-equilibrium reaction model. In most cases the theoretical predictions seriously under-estimated the measured cross sections.

Excitation functions and isomeric ratios for184Re, from -induced reactions on181Ta and natural W have been measured using the stacked-foil method. The data are compared with the theoretical predictions provided by the equilibrium and pre-equilibrium reaction model; for this propose we used the code INDEX development by ERNST.

Excitation functions and isomeric ratios for102Rh, from the -induced reactions on103Rh, have been measured between 15 and 89 MeV. The results show characteristic features of the pre-equilibrium process. The excitation functions were determined by the stacked foil method.

A stack of natural copper was bombarded with -particles. Cumulative cross-sections for65Ga,66Ga and65Zn production, and the excitation functions for68Ga and67Ga production, were measured using high resolution gamma-ray spectroscopy. The data are compared with the theoretical result provided by equilibrium and pre-equilibrium reaction model, for this purpose we used the code ALICE of Blann. The overall agreement with theory is good. Besides, we present the experimental data obtained by other authors.

Cumulative cross-sections were determined by the stacked foil method for the (, xn) and (, 2pxn) reactions on159Tb up to 90 MeV. Thick target yields were calculated as a function of the energy for the production of153Tb,155Tb,156Tb,158Tb and160Tb.
