Excitation of compound states in the subsystems as indirect tool in nuclear astrophysics

Abstract

Astrophysical reactions proceeding through compound states represent one of the crucial part of nuclear astrophysics. However, due to the presence of the Coulomb barrier, it is often very diffi cult or even impossible to obtain the astrophysical S (E) factor from measurements in the laboratory at astrophysically relevant energies. The Trojan Horse method (THM) provides a unique tool to obtain the information about resonant astrophysical reactions at astrophysically relevant energies. Here th e theory and application of the THM for the resonant reactions is addressed.
