Abstract

In this work, bound-free pair production (BFPP) cross section calculations are done for NICA collider. In the BFPP mechanisms, after free pair production process, free electron is captured by one of the ions. This causes to the decrement of the ion from the beam, also diminish the intensity of the beam and changes the beam lifetime. BFPP cross section calculations are done for p-Au and p-Bi collisions for NICA collider and it is seen that the obtained results are in the range of a few mbarns. In this work, we used the lowest-order perturbation theory and our calculations are done in QED framework.
