Abstract  

A stack of natural samarium was bombarded with 87 MeV -particles. Cumulative cross sections for the production of145Eu,146Eu,147Eu,148Eu,150Eu,152Eu and154Eu have been studied using gamma-ray spectroscopy. The data are compared with the theoretical results provided by equilibrium and pre-equilibrium reaction models, for this purpose we used the code ALICE of Blann.

Abstract  

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.

Abstract  

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.

Abstract  

Stacks of natural erbium were bombared with -particles with energie of 85 MeV. Cumulative cross sections for the productions of different nuclei were measured using -ray spectroscopy. The data are compared with the theoretical predictions provided by the equilibrium and preequilibrium reaction model.

Abstract  

Target foil stacks of niobium were bombarded with beams of alpha particles at incident energies ranging from 0 to 90 MeV. Cumulative cross sections for the production of95(m+g)Nb,92mNb,91mNb and90(m+g)Nb were determined by semiconductor gamma-spectrometry of the residual activity of stacked foils. On the basis of the cumulative cross sections, the thick target yields and saturation production rates of niobium isotopes have been evaluated.

Abstract  

Target foil stacks of silver were bombarded with beams of alpha particles at incident energies 90 MeV. Cumulative cross sections for the production of104(m+g)Ag,105(m+g)Ag,106mAg,108mAg,110mAg and111(m+g)Ag were determined by semiconductor gamma-spectrometry of the residual activity of stacked foils.

Abstract  

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.
