Electron-gamma angular correlation arrangement using semiconductor counters

An electron-gamma angular correlation arrangement using a lithium-drifted semiconductor counter as electron detector is presented. This was placed together with a field-effect transistor in a cylindrical rotating vacuum chamber cooled at a temperature of 200°K through a cold-finger system. Three sci...
