Ernest Rutherford predicted the nucleus in 1920, 12 years later his assistant James Chadwick found and confirmed it.
The scattering of alpha particles by a metal foil.
EVIDENCE
He completely changed the atomic model of his time to something that is quite similar to the current model of the atom. His "alpha scattering experiment" provided the evidence that the atom was mainly empty space, and that most of its mass and all of its positive charge was located in a small, dense core(now called the nucleus).
Direct evidence is something that can prove a fact, evidence that someone has seen or heard. Indirect evidence is different because it relates to facts and does not prove a fact on its own. Indirect evidence is also called circumstantial evidence.
You might be looking for the phrase "exonerating evidence".

The Innocence Project is a national litigation and public policy organization dedicated to exonerating wrongfully convicted people, usually through DNA evidence.
Rutherford, Geiger and Marsden discovered the atomic nucleus.
The experimental evidence led Rutherford to conclude that an atom is mostly empty space because most of the particles weren't deflected off of the gold foil in his experiment.
Ernest Rutherford discovered that the nucleus of an atom has a positive charge and discovered the evidence to show the electron field surrounding the nucleus in an atom.
What evidence that rutherford collected does not support Thompson's model

There is a dense, positively charged mass in the center of an atom...
it is awsome
