As far as I know, that equation stems from Henry Poincare.

In my opinion the equation is wrong.

Meant is actually the mass defect, that occurs with nuclear decay. Then 
the energy of the beam is compared to the missing mass of the 
radioactive sample.

Now 'defect' deserves a minus, while 'beam' requires a positive sign for 
its energy.

'mass defect' requires also a delta (delta(m_sample) = m_2 minus m_1).

So:
  - delta(m_sample) = e_beam /c²
