摘要

用(n，γ)反应测定了碳、铝、铁、铜和锌的核半径参数。来自镅-铍源的中子通过(n，γ)反应与水慢化剂相互作用产生2.2 MeV的γ射线。用闪烁探测器和8k多通道分析仪对水介质的γ辐射进行了测量。来自镅-铍源的中子被允许穿过不同厚度的碳、铝、铁、铜和锌元素靶，并且被传输的中子再次被允许与水减速剂相互作用，产生2.2 MeV的γ辐射。通过测量中子通过不同质量数的元素靶所产生的γ辐射的产率，确定了中子相互作用的总截面。通过已知靶核的总中子相互作用截面和质量数，确定了半径参数。

Determination of the nuclear radius parameter using the γ-ray spectrometer

The nuclear radius parameter of carbon, aluminium, iron, copper, and zinc nuclei has been determined by using (n,γ)-reaction. The neutrons from the americium-beryllium source are made to interact with the water moderator to produce the γ-rays of 2.2 MeV through (n,γ)-reaction. The γ-radiation emitted from the water medium is measured with a scintillation detector coupled to 8k multi-channel analyzer. The neutrons from the americium-beryllium source are allowed to transmit through carbon, aluminium, iron, copper, and zinc elemental targets of various thicknesses, and transmitted neutrons are again allowed to interact with water moderators to produce 2.2 MeV γ-radiation. By measuring the yield of γ-radiation produced in water moderators by neutrons transmitted through elemental targets of different mass number values, the total neutron interaction cross-sections are determined. By knowing the total neutron interaction cross-sections and mass number of the target nuclei, the radius parameter has been determined.
