A multi-parameter coincidence detector system consisting of a △Eβ-Eβ telescope
two germanium detectors and a slow clock time-to-digital converter (CTDC) has been set up. For studying neutron-rich nuclei
the △Eβ-γ coincidence is employed to reduce intensity of γ-rays from neutron-deficient nuclei. The CTDC can give nuclear decay time parameters for determining half-life of nuclear decay
showing that this detector system can be used to study nuclear decay scheme.
