Optimization of the number of intrinsic states included in the discrete generator coordinate method

We present a mechanism to efficiently preselect the number of intrinsic many-body states that are used to define the many-body wave functions within the discrete generator coordinate method (GCM). This procedure, based on the proper definition of a natural basis of orthonormal states, does not requi...
