Description	Monoenergetické konversní elektrony z rozpadu 83mKr (1,83 h) jsou výborným nástrojem pro energetickou kalibraci a systematické studium beta rozpadu tritia, které se měří kvůli stanovení klidové hmotnosti neutrina. Z tohoto důvodu jsme připravili mateřský radionuklid 83Rb (86,2 d) reakcemi natKr(p,xn) na cyklotronu U-120M a studovali chování systému 83Rb/83mKr za podmínek, kdy je mateřský radionuklid zakotven v matrici katexového papíru a zeolitu. Z gama spektrometrického stanovení účinnosti emanace 83mKr z matrice se jeví jako perspektivní materiál pro přípravu radionuklidového generátoru 83Rb/83mKr jakožto nástroje ke kalibrací elektronového spektrometru v projektu KATRIN pouze zeolit. (cs) The mono-energetic conversion electrons from the decay of 83mKr represent a unique tool for energy calibration and systematic studies of the tritium beta spectrum measured in neutrino mass determination experiments. For this reason, the corresponding parent isotope was produced in reactions natKr(p,xn)83Rb. The behaviour of 83Rb (T1/2 = 86.2 d) and its daughter product 83mKr (1.83 h) was examined, when the 83Rb was trapped in a cation-exchanger chromatographic paper or in zeolite. Using gamma spectroscopy measurements, recommendations for the production of a 83Rb/83mKr radionuclide generator based on these cation-exchangers and suitable for the neutrino mass determination experiment KATRIN were deduced.
