The photodisintegration of 15N through excited states of the residual nuclei has been studied by measuring the yields of de-excitation gamma rays in a Ge(Li) detector. Cross sections for all observed transitions were deduced from measurements with br

Gamma ray spectra from the reactions 13C( gamma ,n gamma ') and 13C( gamma ,p gamma ') have been measured simultaneously in a Ge(Li) detector at 112 degrees using bremsstrahlung with end-point energies in the range 15-44 MeV in order to study the dec

Some measurements on the angular distribution of thin target radiation produced in a synchrotron are reported using ionization chambers to measure the x-ray intensity. Quantitative agreement has been obtained with the bremsstrahlung-multiple scatteri

An apparatus is described for the measurement of the energy and angular distribution of protons from (γ, p) reactions. A method is presented for obtaining energy spread of 3% for protons of 3 to 15 Mev with a NaI scintillator of 1‐in. diam apertur

Photoneutron reactions in carbon, nitrogen, oxygen, and fluorine were studied in the region of threshold using improved efficiency for the detection of the residual activity. The betatron energy calibration used is based on thresholds of deuterium, b

The cross section of the reaction O/sup 16/(gamma,n)O/sup 15/ is inferred from measurement of the residual radioactivity, at gamma energies of 15.5 to 23 Mev. Resonances are detailed. (T.F.H.)

A new system for control of the x‐ray energy from a 25‐Mev betatron is described. Modifications in the method of energy control and orbit expansion lead to improved operation. Calibration of the energy scale is based on reaction thresholds for D(

The azimuthal variations in the out-of-phase fields of a 3 MeV. betatron have been measured using apparatus of improved sensitivity. The method is described and the out-of-phase field analysed giving the contributions from inhomogeneities in the iron
