• Collective excitations of nuclear matter which have their origin in the short-range interaction between nucleons in nucleus are studied in order to correlate strongly excited level groups in nuclear reactions of relatively high energy with nuclear structure. Making use of an effective inter-nucleon potential which is determined from the analysis of pairing energies of various nuclei, the collective excitation energies are estimated in one particle-hole pair approximation of the new Tamm-Dancoff method. Three stable modes of excitations are possible, that is, spin wave, isospin wave and coupled spin-isospin wave. Of these three modes the spin wave is the lowest exciting wave, the coupled spin-isospin wave is the second and the isospin wave is the highest. Each of them has its own critical momentum above which they become unstable. The strengths of coupling of these exciting waves with particle motion are also estimated. The higher exciting wave has the stronger coupling with particle motion and therefore the larger width of excitation energy. These exciting mechanisms would have some connection with the experimental results on inelastic scattering of nucleons and photonuclear reactions.
