[en] Target problems in heavy ion reaction studies are discussed, including non-uniformity in thickness effects and the inability to fully compensate for reaction-site effects, both problems becoming more serious the heavier the ion. For the non-uniformity effects, the flatness of the target is very critical. Other problems not yet solved are beam-spot heating and the buildup of carbon

[en] Some calculations are given which show the extent of the problem of target non-uniformity in heavy-ion reactions. Nonuniformity effects are exceedingly important for heavy-ion reactions, and the flatness of the target is very critical. The problem of beam-spot heating and the buildup of carbon has not been solved

[en] A detector of the properties of individual charged particles in a beam includes a gridded ionization chamber, a cathode, a plurality of resistive-wire proportional counters, a plurality of anode sections, and means for controlling the composition and pressure of gas in the chamber. Signals generated in response to the passage of charged particles can be processed to identify the energy of the particles, their loss of energy per unit distance in an absorber, and their angle of incidence. In conjunction with a magnetic spectrograph, the signals can be used to identify particles and their state of charge. The detector is especially useful for analyzing beams of heavy ions, defined as ions of atomic mass greater than 10 atomic mass units. 7 claims

[en] The ¹⁶O + ⁴⁰Ca inelastic scattering has been measured at 60-MeV incident energy, and evidence has been found in support of an explicit coupling between direct and elastic channels. The measurements were extended over a large angular range and in particular to very forward angles. The ratio of cross sections between extreme forward and backward angles proved very useful in studying the underlying reaction mechanism

[en] The use of nuclear track emulsions in nuclear physics research is described with particular emphasis on their employment as focal-plane detectors. A brief description of nuclear emulsions and the theory of the photographic process is given in order to sketch the available opportunities to vary their sensitivity and other properties. Data about currently available emulsions are collected. Some practical techniques for using emulsions as focal-plane detectors are described. A summary of the current state-of-the-art for automatic plate scanning is given. (Auth.)
