Isoscalar transition probabilities ({ital B}({ital IS}{lambda})) have been obtained from the analysis of inelastic {alpha} scattering using double-folded optical {alpha}-nucleus potentials. The reliability of the proposed method was tested by applying it to three nuclei representing limiting cases of nuclear structure models. Data on {sup 208}Pb have been analyzed at {ital E}{sub {alpha}}=23.5, 79.1, 104, and 139 MeV using the hydrodynamical model. For {sup 168}Er ({ital E}{sub {alpha}}=36 MeV) the model of the asymmetric rotor and for {sup 108}Pd ({ital E}{sub {alpha}}=30.5 MeV) the model of the harmonic vibrator was considered. Excellent agreement of the extracted {ital B}({ital IS}{lambda}) values with the corresponding {ital B}({ital E}{lambda}) values (obtained from electromagnetic probes) has been reached. The result of a lifetime measurement for the two-quadrupole-phonon 4{sup +} state at 2055 keV in {sup 168}Er has been confirmed.
