“…At present a beam line for electronenergies <140 MeV is equipped with relatively thin convertors (< 0.5 mm W = 0.14 radiation length) and a sweep magnet to provide a 'clean' photon beam -with a continuous spectrumfree of residual electrons [1], Samples to be irradiated are placed in the open air on the axis of the photon beam at about 60 cm downstream from the convertor. External targets are very helpful for controlling irradiation conditions.…”

The Medium-energy Electron Accelerator (MEA) of the National Institute for Nuclear Physics and High-Energy Physics at Amsterdam is since a number of years in operation for carrying out a fullscale program on nuclear physics and radiochemistry. The maximum energy attainable is about 500 MeV and will be raised to about 600 MeV in the foreseeable future. Such energies in combination with beam intensities up to ΙΟΟμΑ render the facility an interesting tool for the production of a broad spectrum of radionuclides. To this end the energy of the electrons is first -in part -converted to a strongly forwardpeaked Bremsstrahlung photon beam, by passage through a sheet of a suitable high-Z element such as Ta or W.At present a beam line for electronenergies <140 MeV is equipped with relatively thin convertors (< 0.5 mm W = 0.14 radiation length) and a sweep magnet to provide a 'clean' photon beam -with a continuous spectrumfree of residual electrons [1], Samples to be irradiated are placed in the open air on the axis of the photon beam at about 60 cm downstream from the convertor. External targets are very helpful for controlling irradiation conditions. For instance, for gasphase irradiations targets can be readily irradiated at elevated temperatures in case of materials with high boiling points.

Abstract.Reactions of "C recoil atoms with C,H, in the presence of 0, lead to the formation of high yields of labelled C,H,CHO in the gaseous (6%) and liquid (&lo%) phase, whereas none was detected in the solid phase. For the liquid phase, 63% of the "C activity in C,H,CHO is in the -CHO group, while 37% is part of the aromatic ring; in the case of gaseous C,H, with 37% 0,, the amount of "C in the ring is only 11 %. The reactions possibly leading to the formation of ["C]C,H,CHO and the "C distribution over the molecule are discussed.

The reactions of recoil 11C atoms with liquid C6H6 result in the production of 11C‐labelled cycloheptatriene (CHT) and toluene in equal amounts of approximately 3%. From the effect of O2 on the product yields it is concluded that recoil labelling proceeds via both singlet and triplet 11CH2 intermediates, whereas 11CH may also contribute specifically to the formation of C6H5CH3. Addition of H2S increases the [11C]C6H5CH3 yield by ca. 5%, probably due to reactions of triplet phenyl‐carbene (C6H5CH). The reactions of singlet CH2, produced via the photolysis of CH2N2, with liquid C6H6 were also investigated in the presence of N2, O2 and I2.
