Ionizzazione totale delle particelle α del polonio in argon e azoto

  • Published:
Il Nuovo Cimento (1943-1954)

Riassunto

L'energia mediaw spesa da una particella del polonio per creare una coppia di ioni in argon e azoto è stata misurata con una camera a griglia. Si è trovato:w argon=28,9±0,6 eV,w azoto=37,9±0.8 eV.

Summary

The total ionization produced by α-particles from Po210 has been measured in pure argon and nitrogen. Argon and nitrogen were purified by a calcium-magnesium filled convection current purifier. Electron collection has been employed, using a fast amplifier feeding an ordinary discriminator. The average energyw spent in producing a ion pair in argon and nitrogen are as follows:w argon=28,9±0,6 eV,w nitrogen=37,9±0,8 eV. Our results are in good agreement with the measurements of Stetter's laboratory.
