Energy of Beta Particles - Ioniserende Stralen Practicum
... The β particles from a 90Sr source do not all have the same kinetic energy. The graph below shows the number of β particles as a function of their kinetic energy. The kinetic energy found in assignment 8 is the energy value that occurs most (Ek in the graph). From other experiments it is known that ...

The rotational energy levels
... Because the classical angular momentum about the axis a is Ja = Ia ωa with similar expressions for the other axes, it follows that E = Ja2 / 2 Ia + Jb2 / 2 Ib + Jc2 / 2 Ic This is the key equation, and can now make use of them in conjunction with this equation to obtain the rotational energy levels. ...
