Nature of problem: Radial matrix elements for E2 or M1 Coulomb excitation are calculated for l values up to 500. These elements are used in the calculation of scattering amplitudes associated with inelastic scattering of charged particles from nuclei, by partial waves expansion. When non-Coulomb short range forces are included, these elements apply to large l values. Coulomb interaction is important even at energies high above the Coulomb barrier, and a few hundred partial waves have to be included. | ||
Restrictions: Quadrapole matrix elements can be calculated up to l=500 at most. Reasonable accuracy can be achieved only with xi/eta ~>0.003 (projectile's energy up to 170 times the excitation energy). For xi/ eta<~10**-2, the accuracy of 10**-7 cannot be acquired. |
