摘要

在0·0167 ~ 0·0342 cm−2的屈曲范围内测量了BeO体系的衰减常数。相应的衰减常数范围从低于恒定碰撞频率极限λ*到高于弹性连续界λel。实验确定了λel(B2)的范围,并与基于GASKET规范生成的截面数据的计算值进行了比较。

Pulsed-neutron decay measurements on BeO systems in the vicinity of the continuum bound

Decay constants have been measured in BeO systems in the buckling range 0·0167–0·0342 cm−2. The corresponding decay constants range from below the constant collision frequency limit, λ*, to values above the elastic continuum bound, λel. A range of λel(B2) has been determined experimentally and the results are compared with calculated values based on cross-section data generated by the GASKET code.
