[en] A radioactive ion beam of ⁶He produced via the ⁷Li (p,2p) ⁶He reaction with typical intensity of 3x10⁶ was elastically scattered from LiF (Au) targets. Elastic scattering of ⁶He at E_lab = 27 MeV with ¹⁹⁷Au have been measured in the angular range of 6 ^dig-72 ^dig in the laboratory system employing lead and lamp detection system. Optical model calculations have been used to fit the data

[en] The Ion Beam Techniques have opened a new window to study crystal structures and imperfections of crystals. In this paper, we try to briefly describe concepts and applications of Rutherford backscattering spectroscopy-Channeling to determine crystal parameters and disorders. Some experimental results of the analysis of semiconductor materials are presented in this paper, which has been obtained by means of Rutherford backscattering spectroscopy-Channeling technique

[en] Interaction of energetic ion beam with matter results in atomic excitation and ionization of matter which consequently leads to occurrence of the characteristic X-rays fluorescence. In the interaction of energetic molecular beam with matter, the unique phenomena of ^Vicinage effect^and ^Coulomb explosion^have already been observed and reported. In this research work, the interaction of molecular ion beam with targets of different atomic numbers was investigated. For this purpose, the yields of characteristic X-rays due to interaction of H₂⁺ molecular ion beam with the selected targets were compared with those due to interaction of H⁺ atomic beam with the same targets. To accomplish this, atomic and molecular beams in the energy range of 1 to 1.4 MeV/u were used to irradiate targets of different atomic numbers, including Cu, Mn and Al. For Mn and Cu. The measured yields of the characteristic X-rays due to the irradiation by the atomic and molecular beams were found to be approximately the same. However, for the Al target, a significant difference was observed for the X-ray characteristic yields due to the irradiation by the atomic and molecular beams.

[en] Finding the distribution of elements in a given sample is very important in biology, microelectronics and geology. By using a microbeam and scanning the samples, we can obtain a great deal of information about the distribution of elements. After the installation of a microprobe system in the Van de Graaff Laboratory, we started applying this system. In this paper, we report some preliminary results on the distribution of elements in archaeological, geological, microelectronic samples. The aim of this paper is to describe the capabilities of the microprobe system in material analysis

[en] The ¹⁵N+p scattering differential cross section has been measured in the c.m. energy region of 0.57 to 1.4 MeV by bombarding a proton-rich target with a ¹⁵N beam. The recoiled protons have been detected in angular range θ_tab=8^deg^- 18^deg^using the LEDA detector system. The measured differential cross section in θ_tab=8.2^deg^shows the resonances at MeV and MeV proton energies.
