We used recent phenomenological form factors to calculate the effect of on-shell two-pion exchange in nucleon-nucleon scattering below the two-pion production threshold. As expected, the contributions of partial wave a ...

The purpose of this investigation was to explore how differences in an elementary mathematics teacher's subject matter knowledge structure impact classroom teaching and student learning. The study included two phases. Ph ...

The purpose of this study was to examine whether teaching materials designed around fourth graders' preconceptions effectively produced conceptual change about light propagation. Four Taiwanese fourth-grade intact clas ...

The microscopic, momentum space, optical potential description of spin 1/2 x 1/2 scattering is extended to include the coupling of the singlet-triplet spin channels and the exact handling of the Coulomb force. Computing ...
