【摘要】 在2.5MeV脉冲化质子静电加速器上,用T（p,n）³He中子源,使用大液体闪烁探测器和飞行时间技术,以¹⁹⁷Au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₆₀Nd和₆₂Sm的辐射俘获截面。测量结果与其它数据进行了比较。更多还原

【Abstract】 The fast neutron-capture cross sections or elemental neodymium ana samarium wer-measured in energy range of 0.34-1.68MeV relative to the standard capture cross section of gold. The T(p,n)*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.更多还原
