In the latest edition of the journal Nature Prof. Polasik from the Faculty of Chemistry of the Nicolaus Copernicus University in Toruń published an article describing the observation of the forced release of energy from the excited atomic nuclei.
Co-author of the publication  “Isomer depletion as experimental evidence of nuclear exclusion by electron capture” is Dr Jacek Rzadkiewicz from the National Center for Nuclear Research in Świerk.
The authors report the first experimental observation of a new, theoretically foreseen physical phenomenon, i.e. the process of excitation of the nucleus through the electron capture to the atomic electron shell.
The experiment was conducted in the United States with the linear ATLAS accelerator at the National Laboratory in Argonne.
