摘要

由于64Zn（n

α）61Ni反应的剩余核是稳定的

不能用通常的活化法来测量

致使该反应截面实验数据缺乏。利用双屏栅电离室作为带电粒子探测器

在En=2.54

4.00

5.03

5.50与5.95MeV5个能点

对64Zn（n

α）61Ni反应的微分截面进行了实验测量

并通过微分截面对角度的积分得到了反应截面。实验在北京大学4.5MV静电加速器上进行。2.54MeV的单能中子采用固体氚-钛靶T（p

n）3He反应产生

其余四种能量的准单能中子通过氘气体靶D（d

n）3He反应获得。绝对中子通量采用238U（n

f）反应来确定

实验过程中用BF3长中子计数器进行相对中子通量监测。测量结果与已有的实验与评价数据进行了比较。

Abstract

Activation method is not feasible for 64Zn(n

α)61Ni reaction cross section measurement because the residual nucleus 61Ni is stable.This leads to scanty of the experimental data for the 64Zn(n

α)61Ni reaction.By using a twin-gridded ionization chamber

differential and angle-integrated cross section data of the 64Zn(n

α)61Ni reaction were measured at neutron energies of 2.54

4.00

5.03

5.50 and 5.95 MeV.The experiment was performed on the 4.5 MV Van de Graaff accelerator of the Institute of Heavy Ion Physics

Peking University

China.Monoenergetic neutrons of 2.54 MeV were produced through the T(p

n)3He reaction with a solid Ti-T target

and those of the other four energy points were produced through the D(d

n)3He reaction with a deuterium gas target.The absolute neutron flux was determined through the 238U(n

f) reaction and a BF3 long counter was used as the neutron flux monitor.Results of present work are compared with other measurements and evaluations.
