„THE TROJAN HORSE METHOD IN NUCLEAR ASTROPHYSICS”
prelegent: prof. Claudio Spitaleri (Dipartimento di Fisica e Astronomia, Catania University, Catania, Italy and INFN, Laboratori Nazionali del Sud, Catania, Italy)
Streszczenie: Alternative methods for determining bare-nuclei cross sections of nuclear reactions for astrophysics are needed, because of the intrinsic limitations in the direct experimental study. In this context, a number of indirect methods, e.g., the Coulomb dissociation, the ANC (asymptotic normalization coefficient) method, and the Trojan-Horse Method (THM) have been developed and successfully exploited over the last decades. In particular, the THM has proved to be an extremely useful and versatile approach to extract nuclear reactions of astrophysical relevance which turns out to be insensitive to the screening effect and allows to determine the energy dependence of the reaction cross section in the region of astrophysical interest. The key ideas on which the method is based and the the recipe to extract data are presented.
