3,3 resonance and Nucleon pole model forpp→ppπ0 andpp→pnπ+

1974

The Nucleon pole and 3,3 resonance pole contributions are considered for the reactionspp→ppπ0 andpp→pnπ+ at low and medium incident proton energies. The total and various differential cross sections are calculated, also for polarized nucleons, and compared with experimental data.

On screening effects in pair production at intermediate and high energies

1972

The effect of screening in atomic field pair production is calculated in Born approximation without approximation as to energy or angle and compared with the results of previous calculations based on the high energy approximation. The difference between the two calculations is comparable to the errors in recent experiments. The effect of nuclear excitation on the total pair production cross section is also investigated, but is found to be extremely small.
