The Trojan Horse method in nuclear astrophysics
The Trojan Horse method (THM) is an indirect method based on quasi-free reactions (QFR) for studying nuclear reactions of interest for nuclear astrophysics.
Recently we applied this method to the study of nuclear reactions that involve radioactive species, namely to the study of the 18F+p-->15_O+alpha process at temperatures corresponding to the energies available in the classical novae scenario. The experiment was performed in two runs at the CRIB apparatus of the Center for Nuclear Study of the University of Tokyo and results of the data analysis will be presented.
A method closely related to THM has also been implemented to study processes induced by neutrons. We recently applied this technique to the study of the reaction 6Li+n->3H+4He as a test case and other reactions are presently being considered. This technique is particularly interesting when applied to reaction induced by neutrons on unstable short-lived nuclei. In this case, direct measurements are practically impossible. Such processes are very important in the nucleosynthesis of elements in the s- and r-processes scenarios and this technique can give hints for solving key questions in nuclear astrophysics.
