The 60-in. scattering chamber used with the external beam of the Argonne 60-in. cyclotron is described. The scattering chamber permits operation over an angular range from 4 deg to 176 deg with an accuracy of plus or minus 3 min. of arc. The geometrical factors involved in the measurement of cross sections are known to plus or minus 0.1% or better. The angular positions of the detectors, the target changer, and an absorber foil system in front of the detection units are operated by remote control so as to permit continuous operation of the cyclotron when these parameters are varied. It is possible to operate several detectors simultaneously; and in order to permit angular correlation studies, the angular position of one detector can be varied by remote control with respect to the other detector units. A summary of some of the experimental work performed with this instrument is given. (auth
