Investigation of proton and deuteron induced reactions on cobalt

In the framework of a systematic study on light ion (p, d) induced reaction on different targets of medical, industrial, etc. importance, natural cobalt has been investigated by using stacked-foil technique. In these measurements C-55,C-56,C-57,C-58,C-60 isotopes have been identified. Beyond the Cobalt isotopes we have also presented Ni-57 and Mn-52 from the proton experiment. For the above isotope the excitation functions in the measured energy range were determined and compared with the literature data and with the results of model calculations. The agreement with previous measurements was good and we have also measured new cross-section data

Experimental and theoretical study for the production of 51Cr using p, d, 3He and 4He projectiles on V, Ti and Cr targets

Production of 51Cr (T1/2 = 27.7 d) have been studied experimentally through the reaction of proton and 3He on natV and natTi targets respectively by using a variable energy cyclotrons. Reaction cross sections were obtained at different energies using the stacked-foil technique. High resolution gamma ray spectrometers were used for measuring the c-ray spectra. Comparison between the present experimental results and the previously reported data has been carried out and discussed. The possibility of producing 51Cr with reasonable yield using different projectiles and different natural targets was studied and reported. Excitation functions for the reactions of proton, deuteron, 3He and 4He particles on natural vanadium, titanium and chromium targets have been evaluated using two theoretical codes TALYS-1.6 and EMPIRE- 3.1. The recommended cross-sections and the integral yields as well were obtained

Measurement of surface wear using the thin layer activation (TLA) technique

The thin layer activation (TLA) technique is being used to measure the continuous wear of piston rings and cylinder liners in the nm to μm range. The procedure, effectively using a radioisotope tracer, involves two main steps. Firstly the surface of interest is activated using a charged particle beam and secondly its wear characteristics are tested using a special tribometer set-up. The whole procedure will be discussed along with technical factors to be considered (including the different nuclear reactions used to study different elements) and its limitations. Other known and potential applications will also be described

Activation cross sections of the 169Tm(d,2n) reaction for production of the therapeutic radionuclide 169Yb

Activation cross sections of deuteron induced nuclear reactions on (169)Tm were measured up to 20 MeV by using the stacked-foil technique. Special emphasis was on production of the internal radiotherapy related radionuclide (169)Yb. No earlier experimental cross-section data on deuteron induced reactions on (169)Tm were found in the literature. The experimental data were compared with the results of the nuclear model codes ALICE-IPPE and EMPIRE-II. The integral yield of the (169)Tm(d,2n)(169)Yb reaction was deduced over the optimum energy range Ed = 20-->9 MeV. At 3.8 MBq/microA.h the yield is lower than that available from the commonly used (168)Yb(n,gamma) (169)Yb reactor method but on the other hand, it is higher than the yields from the earlier investigated (169)Tm(p,n)(169)Yb and (nat)Er(alpha,x) (169)Yb reactions
