英文摘要	The beta-decay of N-18 has been studied using beta-n and beta-gamma coincidence methods. The N-18 ions were produced by the fragmentation of the E/A=68.8 MeV Ne-22 beam on a thick beryllium target. A newly constructed neutron detector system with wide energy detection range and low-energy detection threshold was used. The 619 +/- 2 ms half-life of the N-18 beta-decay was found to be in very good agreement with the previous measurements. Transitions to 11 beta-delayed neutron emitting states in O-18 have been observed with a total branching ratio of 6.98 +/- 1.46%. The Gamow-Teller beta-decay strengths of N-18 to these levels were deduced and compared with the shell model calculations. The intensities of the strong gamma-ray transitions in O-18 were found to be consistent with recent work.
