A replica of an apparatus used by Geiger and Marsden to measure alpha particle scattering in a 1913 experiment. The Rutherford scattering experiments were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated.
An diesen Experimenten waren unter Ernest Rutherfords Leitung Hans Geiger und Ernest Marsden beteiligt. Bei der Betrachtung der Messergebnisse, die darauf hinweisen, dass die Masse des Atoms in einem kleinen Kern konzentriert ist, soll Rutherford gesagt haben: „Dies ist so unwahrscheinlich, als ob man mit einer Pistole auf einen ...
Rutherford backscattering spectrometry is named after Lord Rutherford, a physicist sometimes referred to as the father of nuclear physics. Rutherford supervised a series of experiments carried out by Hans Geiger and Ernest Marsden between 1909 and 1914 studying the scattering of alpha particles through metal foils.
Rutherfords Mitarbeiter Hans Geiger und Ernest Marsden führten Versuche mit energiereichen Alpha-Teilchen der natürlichen Radioaktivität von Wismut-214 durch. Zunächst wurde beobachtet, dass einige wenige der Alpha-Teilchen von einer Platinplatte zurückgeworfen wurden.
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 ...
Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect.
12. Feb. 2022 · The Geiger-Marsden experiment, also called the gold foil experiment or the α-particle scattering experiments, refers to a series of early-20th-century experiments that gave physicists their...
