Cs-137 energy spectrum

WebBeta Spectrum Goal: to investigate the spectrum of β rays emitted by a 137Cs source. The instrument used is a so-called 180o magnetic spectrometer that separates β rays of different momenta by using a magnetic field. 1 Introduction 1.1 Beta decay The continuous spectrum of β rays (electrons) from a radioactive source is explained WebCaesium-137 is one such radionuclide. It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable.

Caesium-137 ( 55Cs ), cesium-137 (US), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission … See more Caesium-137 has a half-life of about 30.05 years. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m ( Ba, Ba-137m).
