Summary on Grant Application Form |
This proposal addresses some key issues in the acquisition of nuclear physics data from laboratory experiments for application to calculations of rates for astrophysically relevant nuclear reactions. Their knowledge is crucial for reliable predictions of the evolution of stars and the chemical evolution of the Universe.This proposal concerns an important class of radiative proton and alpha-particle capture reactions, important in nucleosynthesis and energy production in stars. The cross sections of these processes at low stellar energies are extremely small and consequently they are very difficult to measure especially when an unstable nucleus is involved. We propose to explore a quantitative link between the information obtained from laboratory experiments with beams and targets of stable nuclei at energies where cross sections are large, and information about collision rates for unstable nuclei of importance in stars. The proposed link is deduced from the symmetry of nuclear forces under the interchange of neutrons and protons, a symmetry which is known to be valid to high precision.A by-product of the study will be the development of a new method for the absolute calibration of nuclear reaction theories of interest to nuclear structure research.
