Abstract

Abstract

The Neutron importance in the hole cross bare ²³⁹Pu shell was measured using long counter and gained the neutron importance distribution. The distribution configuration is well consistent with calculation results. The data shows that the distribution is M type, the maximum value is 1.02 times of the center, and the value on the surface is about 65% of the center.
