Well, it was discovered by a group of french scientists and I think it was discovered using an EBIT.

Do you mean, how did scientists discover that atoms were "hollow"?
A scientist named Rutherford took some gold foil (which can be made extremely thin) and bombarded it with alpha particles (Helium nucleuses). He put detectors in a semicircle around the foil to measure the scatter of the alpha particles, and expected a normal distribution around the semicircle of scattered alphas -- IF atoms were 'solid' as they thought.
He was suprised toi find most of the alpha's went straight through the foil to the detector opposite the alpha source.
Because of this it was clear that atoms were mostly "space", or hollow.

Rutherford and alpha-particle scattering from gold leaf. For gold, atomic diameter is around 1.3x10^(-10) meter, nuclear diameter is round 7.3x10^(-15) meter. Gold nuclear volume is then about 5.6 trillionths of gold atomic volume

"Hollow" is not the correct word.
