Abstract

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.
