English Dictionary

branching ratio

名詞

In radioactivity, the portion of all decays that take a given pathway. For example, californium-252 decays by alpha decay ~97% of the time, and by spontaneous fission ~3% of the time; so the branching ratio is about 0.97 in favor of alpha decay, and about 0.03 in favor spontaneous fission.

日本語の意味

放射性崩壊における全崩壊のうち、特定の崩壊経路によるものの割合。

To predict the outcomes of nuclear decay experiments, scientists carefully measure the branching ratio of californium-252 between alpha emission and spontaneous fission.

核崩壊実験の結果を予測するために、科学者たちはカリホルニウム252のアルファ崩壊と自発核分裂の間の分岐比を慎重に測定する。
