A simple optical detector of position versus time providing submillimeter spatial and nanosecond time resolution is described. The spatial beam profile of a nanosecond‐pulse‐width nitrogen laser is sampled simultaneously when the UV light strikes

The reaction ${\mathrm{C}}^{13}(p,\ensuremath{\gamma}){\mathrm{N}}^{14}$ has been studied experimentally for proton bombarding energies between 0.4 and 2.7 MeV. Targets of carbon enriched in the isotope ${\mathrm{C}}^{13}$ were prepared, and thick an

Transmission measurements of the total neutron cross section of deuterium have been made with an accuracy of about 2 percent at 29 energies between 0.2 and 22 Mev, using deuterium gas in a cell 1 meter long. The cross section decreases monotonically

The yield of ${\mathrm{N}}^{13}$ from a thick carbon target bombarded with protons of energy up to 2.5 Mev has been studied by detecting annihilation quanta with a scintillation crystal. Resonances at 0.45 and 1.70 Mev are confirmed, and independent
