Production Cross–Section Calculations of 62Cu via Charged Particles Induced Reactions

The utilization of radioisotopes has been increasing proportionally with the scientific and industrial developments. Among many known and used examples of them, 62Cu has a wide usage due to its suitability for many specific requirements such as in medical applications. By considering the importance of radioisotopes and especially 62Cu, in this study, the theoretical calculations of cross–section values for 62Cu via 59Co(α,n)62Cu, 61Ni(d,n)62Cu, 62Ni(d,2n)62Cu and 62Ni(p,n)62Cu reactions were carried out by employing three phenomenological level density models via TALYS 1.9 code. Obtained results were compared with the available experimental data from Experimental Nuclear Reaction Data (EXFOR) Library by graphically and mathematically.

Progress in international collaboration on EXFOR library

The EXFOR library has served as the unique repository of experimental cross section and other nuclear reaction data for 50 years. The Nuclear Reaction Data Centres (NRDC) have compiled data sets from more than 22000 experimental works for the EXFOR library. Our collaboration and effort on improvement of EXFOR coverage are described in this paper, as well as tools for digitization of numerical data from graph images developed by us for EXFOR compilation.

A computational EXFOR database

The EXFOR library is a useful resource for many people in the field of nuclear physics. In particular, the experimental data in the EXFOR library serves as a starting point for nuclear data evaluations. There is an ongoing discussion about how to make evaluations more transparent and reproducible. One important ingredient may be convenient programmatic access to the data in the EXFOR library from high-level languages. To this end, the complete EXFOR library can be converted to a MongoDB database. This database can be conveniently searched and accessed from a wide variety of programming languages, such as C++, Python, Java, Matlab, and R. This contribution provides some details about the successful conversion of the EXFOR library to a MongoDB database and shows simple usage examples to underline its merits. All codes required for the conversion have been made available online and are open-source. In addition, a Dockerfile has been created to facilitate the installation process.

Nuclear Data Relevant to the Production of Radioiodine I-123, I-125 by Indirect Route and Medical Applications

The use of radioactive Iodine plays an important role in the treatment of some diseases and diagnosis of others, since they have suitable half-life. The radioactivity emitted from the dissolution of radioactive I-123 and I-125, such as the emission of Auger electrons, positrons and gamma rays reduce the spread of these diseases. Therefore, in this work we discuss the Iodine production via indirect reactions. In order to calculate the cross sections of these reactions for the mentioned target elements, we recommended the cross sections for EXFOR library using the recom.m program, which is written in the present work using Matlab-8, the data are taken from different authors. In order to supply accurate databases for different practical purposes such as proton beam energy monitoring, I-123 and I-125 radioisotopes production, we have evaluated the cross section collected from IAEA for EXFOR library measured by different authors of (p,xn), (d,xn) nuclear process. The selected data and our recommended cross sections were developed for practical applications. Since the preliminary overview of the cross section measurements up to 160MeV showed that there are discrepancies between the literature results.
