Nuclear processes not only generate the energy and drive the evolution of stars, but also are responsible for the synthesis of the elements in the Universe. Helium (He, or ) is the second most abundant element after hydrogen, thus -particle induced reactions such as , and play a crucial role in nuclear astrophysics, especially for understanding stellar helium burning. Direct measurement of the cross sections for these -capture reactions at stellar energies is greatly hindered because of the strong Coulomb repulsion. Alpha-cluster transfer reaction is a powerful tool for investigation of astrophysical , and reactions since it can preferentially populate the natural-parity states with an -cluster structure which dominantly contribute to these astrophysical -capture reactions during stellar helium burning. In this review we summarize the theoretical scheme, the experimental technique, astrophysical applications and the future perspectives of such approach based on -cluster transfer reactions.
