Ernest Rutherford's famous gold foil experiment involves the scattering of alpha particles as they pass through a thin gold foil.
It led to a better understanding of the structure of atoms.
It's also known as the Geiger--Marsden experiment, after Hans Geiger and Ernest Marsden who performed it under Rutherford's supervision.
Particle physicist Bruce Kennedy explains wit this modern re-creation.

So useful. Its good to know that someone out there knows what he's doing.

My dog was barking at the door all through this. Good way to link
Rutherford's experiment with Cern.

I thought gold consist of millions of atoms. The one shown here only has
one atom (nucleus).
That bell is ... ( 8 months ago por DutchPhlogiston)
That bell is extremely annoying and distracting. After the first 2 rings,
its not funny anymore.

how to detect when ... ( 9 months ago por Jay Jain)
how to detect when there is head to head collision of alpha particles
i.e when alpha particles rebound by the angle of 180°

Marvin Cervantes:"the brass can? does brass behave the same way that Lead
did back in Rutherfords day?"
Brass and pretty much most metal will work because it stops alpha
particles. The gamma ray will mostly pass through and they will hit the
detector head on. All you need to do is remove the gamma ray counts from
the counter.

Does that ringing ... ( 7 months ago por Anish Jaywant)
Does that ringing bell tells us that alpha particle is detected by alpha
detector..and yeah those detectors must be present @ angel of 180 Degree

That's my father. He was a really intelligent guy and I am still so proud
of him. <3
I say 'was'.... he passed away from cancer in 2013.
But it's nice knowing that if I want to hear his voice again all I have to
do is watch this video.

Maybe i sound stupid but.. How can there be particles of a particular
charge all disposed in a container?

The gold foil is ... ( 1 month ago por Harry Brielmann)
The gold foil is 1.5 microns thick, and the gold atoms atoms are in the
nanometer range... how many layers of gold atoms does the helium nuclei
need to avoid to pass through without deflection? Thousands? ....Why is
only one gold atom shown in the model? That doesnt look like an accurate
model to me. How frequently are the alpha particles being emitted? Does
gold foil that thick present an effectively solid wall of gold? If helium
nuclei pass through easily, how about helium atoms? How about water?
Wouldnt a pin-ball sort of behavior be expected for the alpha particles?
Helium is a noble gas, but a helium with a +2 charge would be an incredibly
reactive ion, desperately seeking electrons...could it react chemically??
These are the sorts of questions that anyone would wonder about. I do.
