用XMASS-Ⅰ型探测器及其标定装置测量了液体氙的闪烁衰减时间常数。通过比较观测到的光子探测时间和蒙特卡罗模拟计算了电子反冲和核反冲的闪烁衰减时间常数。两个指数分量，对应于单重态和三重态的氙激发二聚体，需要重现所观察到的光子检测时间。本文报道用XMASS-Ⅰ探测器测量电子反冲和核反冲闪烁衰变时间常数。
The scintillation decay time constant in liquid xenon was measured using the XMASS-I detector and its calibration setup. The scintillation decay time constants of both electron recoil and nuclear recoil were evaluated by comparing the observed photon detection times with Monte Carlo simulations. Two exponential components, corresponding to the singlet and triplet state of the xenon excited dimer, are needed to reproduce the observed photon detection times. In this paper, we report the measurement of the electron recoil and the nuclear recoil scintillation decay time constants with the XMASS-I detector.
