Physics Potential of the e-RHIC Based FEL-Nucleus Collider

The main parameters of the FEL–RHIC collider are estimated. The physics search potential of this machine is illustrated using excitations of the 232Th nucleus as an example. It is shown that, due to the tunability and monochromacity of the FEL beam and high statistics, the proposed collider will play an important role in the field of "traditional" nuclear physics. In addition, spin and parity of nucleus excitations can be easily identified at FEL-nucleus colliders.
