摘要

用ＣＲ－３９迭层探测器测量了４４ＧｅＶ或１８ＧｅＶ１２Ｃ离子轰击Ｃｕ靶或Ｐｂ靶时中子产额与入射粒子能量以及靶核质量的关系。当入射能量由１８ＧｅＶ增至４４ＧｅＶ时，Ｃｕ靶的中子产额增大２．１２±０．１９倍，Ｐｂ靶的中子产额增大２．０４±０．１５倍。Ｐｂ靶和Ｃｕ靶中子产额之比在４４ＧｅＶ和１８ＧｅＶ分别为２．５４±０．２０和２．５６±０．２０。

Abstract

The dependences of neutron yield on incident energy and atomic mass of the target have been studied by bombardment of 44GeV or 18GeV 12C ions with Cu or Phtargets. The CR-39 stacks are used to detect fast neutrons. The neutron yield ratios obtained for 44GeV and 18GeV are 2.12± 0.19（Cu target） and 2.04±0.15（Pb target）.The neutron yield ratios obtained for Ph and Cu target are 2.54±0.20（44GeV） and 2.56 ± 0.20（18GeV）

showing that Pb target produces more neutrons than Cu target in the same conditions.
