Analysis of eigenvalues for the energy dependent potentials and NN interaction in the quark compound bag model

The trajectories of eigenvalues of the energy dependent potentials are discussed for the case of NN interaction in the quark compound bag (QCB) model. It is shown that the asymptotic behaviour of eigenvalues for the linearly energy dependent potentials is defined by the coefficient at the linear energy term in the potential. In the QCB model this coefficient depends on the nucleon component admixture in the bag wave function. The results of eigenvalue analysis are illUstrated with the simple example of the QCB potential describing phase shifts up to T<=0.8 GeV
