The presented thesis provides an experimental study of the K-shell double vacancy production in the electron capture decays of 55 Fe, 54 Mn, 65 Zn using a pair of Timepix3 detectors. Measured data are preprocessed and explored. The methodology for the cal- culation of the probability of K-shell double vacancy production in 55 Fe and 54 Mn is developed. Therefore, an extensive amount of signal and background processes were con- sidered during the development of the methodology. The measurement setup is defined and optimized in the Allpix2 framework for a simulation of detection efficiencies of par- ticles participating in the signal and background processes. The probability of K-shell double vacancy creation in the electron capture decay of 55 Fe was measured to be PKK = (1.406 ± 0.05) × 10−4 with a systematic error of ∆sys(PKK) =+0.030 −0.034 ×10−4 . The value of PKK for the electron capture decay of 54 Mn found to be PKK = (3.93 ± 0.44) × 10−4 with a systematic error of ∆sys(PKK) =+0.25 −1.11 ×10−4 . Resulting probabilities for K-shell double vacancy production in 55 Fe and 54 Mn are in agreement with the latest results. 1
