electron is a matter

low atomic mass elements are easily available

with low atomic mass coulombic attaraction is less and greater probability of making electron free

with low atomic mass coulombic attaraction is high and greater probability of making electron free

with low atomic mass coulombic attaraction is less and lesser probability of making electron free

it is easy to produce

it has very small wave length

x-ray photon has very high energy

it is a X-ray diffraction experiment
