In this experiment, we investigate and verify the random behavior of radioactive … 웹Half-life is the amount of time needed for one half of a given quantity of a substance to decay. Half-lives as short as 10 –6 second and as long as 10 9 years are common. In this experiment, you will use a source called an isogenerator to produce a sample of radioactive barium. The isogenerator contains cesium-137, which decays to produce ...
웹2024년 1월 4일 · The purpose of this experiment is to measure the half-life of barium-137 (137mBa). More precisely, students will start with a sample of cesium-137 (137Cs) that will decay into an excited state 137mBa which has a half-life of only a few minutes. When the 137mBa decays into the ground state of 137Ba, it emits a gamma ray
