~(98)Mo中子俘获截面的实验测量及Monte Carlo修正

A 4πtotal absorption barium fluoride detector GTAF(Gamma-ray Total Absorption Facility)has been designed and built amply by the CIAE(the Chinese Institute of Atomic Energy)for accurate measurements of neutron capture cross sections in the keV energy range.

为了精确测量keV能区的中子俘获截面,中国原子能科学研究院经过详细的讨论研究设计提出建造了一套4π全吸收型BaF_2γ探测器GTAF(Gamma-rayTotal Absorption Facility),该探测器对γ射线有很高的探测效率和很好的能量及时间分辨,并且由于其时间分辨在600ps左右,所以俘获中子的能量可以通过飞行时间来测定。
