摘要

LSPN是一类新型有机液态闪烁体。它分为含

B的LSPNJ和含

127

I的LSPNI两种。前者主要用于测量热、慢中子，而后者则用于测量快、慢中子。LSPNJ可作在线监测，而LSPNI则能避开强

场的干扰作离线测量。它们的测量误差小于10%，而测量效率可达70%以上。

Abstract

A new species of organic liquid scintillator

called LSPN

is invented by the authors. It has two kinds of subgroup

LSPNJ and LSPNI

containing

B and

127

I respectively. The former is mainly used for the detection of thermal and slow neutrons

and the latter

of fast and slow neutrons. LSPNJ can be applied in on-line monitoring while LSPNI in off-line so as to avoid the interference of a strong gamma ray field. Their measurement errors are lower than 10% and efficiencies higher than 70%.
