C173700100021 (HPGE)To detect the subsequent gamma ray emission, C173700100022 seven HPGe detectors were positioned with an C173700100023 entrance window distance of about 23 cm to the C173700100024 target.Each detector has a relative efficiency of C173700100025 about 100%, four detectors were surrounded with C173700100026 bismuth germanate (BGO) shields for active C173700100027 background suppression. The total photopeak C173700100028 efficiency of the array was about 0.45%.
