摘要

在2.5MeV脉冲化质子静电加速器上，用T（

）

He中子源，使用大液体闪烁探测器和飞行时间技术，以

Au为标准样品，采用相对测量法，在入射中子能量为0.34—1.68MeV能区测量了

Nd和

Sm的辐射俘获截面。测量结果与其它数据进行了比较。

Abstract

The fast neutron-capture cross sections of elemental neodymium and samarium we??-measured in energy range of 0.34-1.68MeV relative to the standard capture cross section of gold. The T (p

He reaction was used as neutron source and the primary proton beam was accelerated

pulsed and bunched by 2.5 MeV Van be Graaff. A large liquid scintillation detector (680 liter) and time-of-flight technique were used.
