[en] Earlier we reported theoretical studies on the probable production of astatine radionuclides from ^6,7Li- and ⁹Be-induced reactions on natural lead and thallium targets, respectively. The production of astatine radionuclides were investigated experimentally with two heavy-ion-induced reactions: ⁹Be + ^natTl and ⁷Li + ^natPb. Formation cross sections of the evaporation residues, ^{207,208,209,210}At, produced in the (HI,xn) channel, were measured by the stacked-foil technique followed by off-line γ spectrometry at low incident energies (<50 MeV). Measured excitation functions were interpreted in terms of a compound nuclear reaction mechanism using Weisskopf-Ewing and Hauser-Feshbach models. Measured cross-section values are lower than the respective theoretical predictions.
