Study of Borromean halo nuclei by the neutron wall with simulation
《Chinese Physics C》2013年第11期63-66,共4页刘龙祥 孙志宇 岳珂 肖国青 陈熙萌 余玉洪 章学恒 王世陶 唐述文 周勇 闫铎 方芳 
Supported by National Natural Science Foundation of China(10775159,10925526,11079044)
The model of three-body Borromean halo nuclei breakup was described by using standard phase space distributions and the Monte Carlo simulation method was established to resolve the detection problem of two neutrons pr...

Study of the data analysis process of the neutron wall with simulation
《Chinese Physics C》2013年第9期36-40,共5页刘龙翔 孙志宇 肖国青 陈熙萌 余玉洪 章学恒 王世陶 唐述文 周勇 闫铎 
Supported by National Natural Science Foundation of China(10775159,10925526,11079044)
We study the response function of the neutron wall for 300 MeV neutrons with GEANT4 simulations. The methods to find the correct neutron incident position and time are discussed, and the neutron emission angle and ene...
