title: Assembly of an alpha-gamma coincidence measuring device for checking alpha decay schemes.
abstract: Two new chambers for measuring alpha-particle emissions have been made: a low-geometry chamber with a powerful magnet to eliminate conversion electrons, and an alpha-gamma coincidence chamber. Both devices incorporate a high-resolution Si detector, and the second chamber, a low-energy Ge detector as well. A dual parameter multichannel analyzer was used to register coincidences in the second device. Alpha-particle and gamma-ray detectors work simultaneously in both individual and dual modes, providing single and coincidence spectra. Some preliminary alpha-gamma coincidence spectra have been obtained.
