For the metal foil, they tested a variety of metals, but favoured gold because they could make the foil very thin, as gold is the most malleable metal. [16]: 127 As a source of alpha particles, Rutherford's substance of choice was radium, which is thousands of times more radioactive than uranium. [17]
Diagram of the Rutherford gold foil experiment. A fixed-target experiment in particle physics is an experiment in which a beam of accelerated particles is collided with a stationary target. The moving beam (also known as a projectile) consists of charged particles such as electrons or protons and is accelerated to relativistic speed .
After Rutherford's discovery, subsequent research determined the atomic structure which led to Rutherford's gold foil experiment. Scientists eventually discovered that atoms have a positively charged nucleus (with an atomic number of charges) in the center, with a radius of about 1.2 × 10 −15 meters × [atomic mass number] 1 ⁄ 3. Electrons ...
Otto Baumbach (1882-1966) was the glassblower who built part of the apparatus used by Ernest Rutherford and colleagues in the famous Gold foil experiment. [1] [2] In fact, this experiment has been referred to as the Rutherford-Royds-Baumbach experiment: [3]

Aluminum foil is a household item that has about a million uses. We’ll highlight some amazing money-saving uses in this episode of The Saving's Experiment! Unexpected uses for aluminum foil
Now called the Rutherford gold foil experiment, or the Geiger–Marsden experiment, these measurements made the extraordinary discovery that although most alpha particles passing through a thin gold foil experienced little deflection, a few scattered to a high angle. The scattering indicated that some of the alpha particles ricocheted back from ...
But, before you ship your baubles off in the mail or trade them in at a gold party, it's worth while to think about the best way to sell your old. In the last few years, several companies have ...
