Description
Information about various properties of atomic nuclei, as well as nuclear reaction data is often needed in experimental data processing programs. Access to the necessary information could be quite complex because of old-fashion punched card -like format which is used in nuclear structure or nuclear reaction databases. Sometimes there are no experimental information about particular reaction channels so theoretical estimations are needed. The TALYS[1] program for theoretical calculations of nuclear reaction characteristics is a great source of nuclear data. It contains nuclear structure database and library of the nuclear reaction models parameters adjusted to achieve good agreement between calculation and experiment[2]. To simplify access to the calculation results and the TALYS nuclear structure database, we are developing TalysLib. TalysLib is a ROOT[3]-based C++ object-oriented library. It can be used for: 1) extraction and visualization of the calculation results, 2) optimization of the nuclear models parameters using MINUIT package, 3) obtaining of the nuclear structure information from the TALYS database, 4) reading of the pre-processed EXFOR[4] and ENDF[5] files (work in process now) 1.
