摘要

通过测定衰变产物242Cm和242Pu的相对量，测定了242mAm衰变的分支比β−/EC = 5.1±0.1。241Am在材料试验堆中通过中子辐照产生16小时242mAm。测量了反应241Am(n， γ)242mAm的堆中子截面(620±65)。

Branching ratio of 242mAm decay

The branching ratio, β⁻/EC = 5·1 ± 0·1, for ^242mAm decay has been measured by determining the relative amounts of the decay products, ²⁴²Cm and ²⁴²Pu formed. The 16 hour ^242mAm was produced by neutron irradiation of ²⁴¹Am in the Materials Testing Reactor. A pile neutron cross-section of 620 ± 65 barns for the reaction ²⁴¹Am(n, γ)^242mAm was measured.
