The proposal aims as part of the JINA collaboration at the improvedexperimental study of nuclear reactions, relevant for the nucleosynthesis in stellar hydrogen and helium burning scenarios. The measurements are performed at the KN&JN high currentaccelerators at the University of Notre Dame. One ocus of the measurements will bethe study of reactions in the NeNa cycle which is of importance forhydrogen shell burning during late stellar evolution and also for explosivehydrogen burning in novae. For helium burning, the experiments willconcentrate on the measurement of stellar neutron sources during thered giant phase of stellar evolution and in supernovae shockfronts.The experiments are designed for using forward and inversekinematics in a complementary manner. The measurements will be performed using are-circulating gas-target system which can be operated with differentlight and heavy target gas material (H,He,Ne). The reaction productswill be measured with a set of Ge-clover detectors for gamma-radiationand a dedicated Si-strip detector array for particles.
