The 134 Nd required for studies of the violation of the K selection rule for electromagnetic transitions in nuclei with mass numbers around 130 can be produced in the reaction of 122 Te with 16 O. The 122 Te target was prepared by the evaporation in a high vacuum. The deposition of the Te isotope on the backing was performed from the very close distance to economize the usage of the isotopic material. The thickness distribution of the target material determined by measurements of the alpha particles energy loss was estimated as 32%. The first test of the target on the 16 O beam with energy of 80 MeV and intensity of 40 enA proved that target prepared by the Te deposition on the Au backing in vacuum is stable in the in-beam conditions and in spite of its relatively high inhomogeneity is suitable for the planned studies.
The impact of different magnetic field configurations on efficiency of internal conversion electron spectrometer was studied. The CST Particle Studio code allows to simulate electron trajectories in a highly inhomogeneous magnetic field produced by set of permanent magnets. It is shown that the suitable selection of permanent magnets can significantly improve electron transmission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
