New results for the total neutral dissociation cross section and an estimate of the gross cross section for the production of neutral fluorine by electron impact on CF4 have been obtained by combining previously reported results for the total dissociation cross section and the counting cross section for the total dissociative ionisation. This advancement was made possible by recently reported results for multication formation obtained from coincidence experiments. The estimate of the neutral fluorine production cross section is of the same order of magnitude as the total dissociation cross section itself, a similarity which may explain why CF4 is such an effective etching gas. The available cross section data for electron impact energies between 5 and 200 e V are reviewed.

Most of the radioisotopes used in the medical fields, like examination and treatment studies, were produced by employing nuclear reactions. Within the process of a nuclear reaction, one of the most important parameters is the cross-section data, which help reveal the reaction phenomenon's mechanisms. The main intention of this study is to investigate the efficiencies of producing iodine isotopes via 123Sb(α,xn) reactions. For this, optical and level density models of TALYS 1.8 code have been used. Production cross-section, the alpha beam energy, reaction yields, and total activation of radioisotopes have been computed. It has been figured out that a 45 MeV cyclotron could be enough for producing 123-126I radioisotopes with reaction yields of 39.3372, 5.5685, 0.2410, and 0.0796 GBq/mAh, respectively.

Data Points

In this work, we present an attempt to estimate the reaction excitation function based on the measurements of thick target yield. We fit a function to experimental data points and then use three fitting parameters to calculate the cross-section. We applied our approach to 43Ca(p,n)43Sc, 44Ca(p,n)44gSc, 44Ca(p,n)44mSc, 48Ca(p,2n)47Sc and 48Ca(p,n)48Sc reactions. A general agreement was observed between the reconstructions and the available cross-section data. The algorithm described here can be used to roughly estimate cross-section values, but it requires improvements.
