Nuclear astrophysics in storage rings [PDF]
Nuclear Physics A, 1997 Nuclear reaction cross sections are usually very small in typical astrophysical environments. It has been one of the major challenges of experimental nuclear astrophysics to assess the magnitude of these cross sections in the laboratory. For a successful experiment high luminosity beams are needed.

Simulation of a Three‐Nucleons System Transition on Quantum Circuits
Advanced Quantum Technologies, EarlyView.A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.
