The astatine isotopes produced in He3 bombardment of bismuth were analysed with alpha ionization chamber and 100 channel pulse height analyser. The main product was At209 formed by (He3, 3n) reaction. Four other isotopes were also identified. Semi-quantitative calculation of relative yield of each isotope was attempted.
