摘要Ｎｅｕｔｒｏｎｙｉｅｌｄｓａｎｄｅｍｉｓｉｏｎｒａｔｅｓｉｎｔｈｅｆｏｒｗａｒｄｄｉｒｅｃｔｉｏｎｆｏｒ５０ＭｅＶ／ｕ１８ＯｉｏｎｏｎｔｈｉｃｋＢｅ，Ｃｕ，ＡｕｔａｒｇｅｔｓＬｉＧｕｉＳｈｅｎｇ，ＺｈａｎｇＴｉａｎＭｅｉ，ＬｉＺｏｎｇＷｅｉ... Total neutron yields and neutron emission rates in the forward direction for 50 MeV/u 18 O ion on thick Be, Cu, Au targets have been measured using an activation technique. The results indicate that neutron yields and emission rates in the forward direction depend on the atomic number of target nuclei, i.e. the lighter target the greater neutron yield and neutron emission rate. Meanwhile, the neutron yield of 18 O ion is greater than that of 12 C ion when target nucleus and incident energy per nucleon are identical.
