NUCLEAR-STRUCTURE CALCULATIONS IN CONTINUUM - APPLICATION TO NEUTRON-CARBON SCATTERING

An explicit method for calculating the scattering matrix from a given structure-model Hamiltonian is presented. The special technique adopted uses nonorthogonal eigenfunctions of the basic model Hamiltonian to represent the scattering wave functions in the interaction region. Application of this approach is mode to neutron scattering by C12. The weak-coupling particle-rotator model has been used for the positive-parity states of C13. The results obtained agree closely with the experimental total neutron cross section, both the background and resonant behavior being well reproduced by the theory. © 1969 The American Physical Society.
