Іонізація молекули урацилу повільними електронами

Modernization of the hypocycloidal electron spectrometer using a gas-filled cell for measuring the total ionization cross-section of molecules at low electron energies was performed. The measuring method and the method for obtaining the first ionization threshold and appearance energies of ion-fragments were developed. Approbation of theapparatus is carried out for the uracil molecule
