Resonances in atomic nuclei play a vital role in determining rates of astrophysically important nuclear reactions. Efficient experimental technique, Thick Target Inverse Kinematics method, which allows to study properties of resonances in exotic nuclei with radioactive beams using resonance elastic scattering is discussed. Various extensions of this technique for measurements of inelastic excitation functions and application of one of these methods for {sup 7}Be(p,p'){sup 7}Be*(0.43 MeV) reaction is considered.The astrophysical rates of some (alpha, gamma), (alpha, n), (alpha, p) reactions are often determined by the near alpha-threshold resonances. Application of sub-Coulomb alpha-transfer reactions ({sup 7}Li,t) and ({sup 6}Li,d) allow to determine alpha-particle Asymptotic Normalization Coefficients of these resonances with minimal dependance on model parameters. The {sup 14}C(alpha,gamma) reaction is considered as an example for application of this approach.
