Abstract：
A 4π△E_β detector has been set up. Its time response is very good and the rising time is 8ns. By using 4π△E_β-γ coincidence technique, the γ intensity of neutron-deficient nuclides followed by electron capture is strongly suppressed, but the coincidence efficiency about γ line followed by 100% β-decay in neutron-rich Hgnuclides reaches highly 60％. The application of this detector to ¹⁸O＋²⁰⁸Pb experiment made the Compton background descend sharply.
