Why is rutherfords experiment called the gold foil experiment ?

The Rutherfords experiment is called the gold foil experiment because gold was made to create the metal foil. The foil made from gold was only 0.00004 cm thick. The gold foil  helped Rutherford and his associate to prove that a small massive center exists in an atom, which later became known as nucleus.
