2016-04-02 · Cesium-137 has an atomic number of 55, so is written as #""_55^137Cs#. It is also a #beta#-emitter, which means it undergoes #beta#-decay by a neutron decaying into a proton, releasing an electron. Protons and neutrons have the same mass, so the mass number doesn't change. The atomic number increases by one, because one more proton is formed.

137Cs - Comments on evaluation of decay data by R.G. Helmer and V.P. Chechev This evaluation was completed by R.G. Helmer in September 1996 with minor editing done in February 1998. Updating 137Cs half-life and editing were done by V.P. Chechev in February 2006. The literature available by February 2006 was included. 1 Decay Scheme

The decay of 137 Cs has been reinvestigated using several precision counting methods. The emission rate of β-particles plus internal conversion electrons was measured by the 4 π-proportional counter method using vacuum evaporated sources free of self-absorption and checked by the liquid scintillation method. Cs-137 has a nuclear spin of 7/2. It can decay into 3 different Ba-137 levels, the ground state, and two excited states.
