Abstract: [cze] [eng]
Cilem teto prace je změřit intenzity gama rozpadů 83 Rb, ktere se rozpada na stabilni 83 Kr přes metastabilni 83m Kr s monoenergetickym elektronovym spektrem a je tak velmi vhodny na kalibraci experimentů, např KATRIN nebo XENON. Současti prace je i kalibrace detektoru použiteho k měřeni (polovodičovy HPGe tj. High Purity Germanium) pomoci izotopů 241 Am, 152 Eu a 133 Ba se znamymi intenzitami. V praci se podařilo změřit hodnoty intenzit gama přechodů v jadře při rozpadu 83 Rb na 83 Kr, spolu s kalibraci detektoru a zjištěnim zavislosti efektivity detekce na energii. The aim of this work is to measure the intensities of gamma decays of 83 Rb, which decays into stable 83 Kr through a metastable 83m Kr with monoenergetic electron spectrum and is thus very suitable for calibration of experiments, such as KATRIN or XENON. Part of the work is also the calibration of the detector used for measurement (semiconductor HPGe, ie High Purity Germanium) using isotopes 241 Am, 152 Eu and 133 Ba with known intensities. The work managed to measure the values of the intensities of gamma transitions in the nucleus during the decay of 83 Rb to 83 Kr, together with the detector calibration and finding the dependence of the detection efficiency on energy.
