35.介绍了格尔-38慕尼黑达姆施塔特FAIR Phase-0设施DECay SPECTroscopy（DE-37 SPEC）实验系统中使用的FASt TIMing 36阵列（法蒂玛）的γ射线探测的蒙特-卡罗模拟响应。在这种配置中，法蒂玛由36个LaBr 3（Ce）39探测器组成，围绕AIDA，位置敏感带电粒子主动停止-每40个。在FAIR-0设施的第一个DESPEC实验中测量的96 Pd中I π= 8+异构体馈送衰变级联的衰变被用于验证42个模拟。实验结果表明，法蒂玛在106、325、684、44和1415 keV处的全能量峰值效率分别为11.2（11）%、6.8（7）%、3.8（4）%和2.1（4）%，与模拟的45响应值一致。46

35 The Monte-Carlo simulated response for γ-ray detection of the FAst TIMing 36 Array (FATIMA) for exploitation within the the DEcay SPECtroscopy (DE-37 SPEC) experimental system at the FAIR Phase-0 facility at Darmstadt, Ger-38 many is presented. In this configuration, FATIMA consisted of 36 LaBr 3 (Ce) 39 detectors surrounding the AIDA, position sensitive charged-particle active stop-40 per. The decay of the I π= 8+ isomer-fed decay cascade in 96 Pd, measured in 41 the first DESPEC experiment at the FAIR-0 facility was used to validate the 42 simulations. The experimental data yielded in-situ full-energy peak efficiency 43 values for FATIMA of 11.2 (11)%, 6.8 (7)%, 3.8 (4)% and 2.1 (4)% at 106, 325, 684 44 and 1415 keV respectively, consistent with the values derived from the simulated 45 response. 46
