Abstract:

A versatile gamma-ray detecting system has been brought into operation. It is a coincidence-anticoincidence GeLi-NaITl spectrometer, mounted on a turntable to permit the measurements of angular distributions of gamma radiations, produced by nuclear reactions involving charged particles. It consists of a central 20 cc GeLi detector surrounded by a large NaITl annulus which is split into two optically-insulated halves. The method of processing events allows four different spectra to be stored simultaneously under identical gain conditions. Initial experiments using this system are outlined, as well as possible future uses and developments. For purposes of comparison, other new systems are described. Author
