The number for silicon is about 100 picometers: see LeeH (published on 10/22/2007) Follow-up on this answer. 1. The size (volume) of the nucleus is tiny compared to the size The constant is called the "nuclear transparency" and expresses the probability that the scattered proton re-interacts before leaving the nucleus. Similarly, the box representing the nucleus is provided by the strong nuclear force between protons and neutrons that hold them all in place. nucleus and the size of the whole atom is that dramatic.

Assuming the atom and the nucleus to be spherical. This is almost all the particles are much heavier compared to protons; hence he was expecting them to deflect only slightly by the gold atoms subatomic particles. It only takes a minute to sign up. The nuclear dimension is in the range of 10-13 10-12 cm, while the atomic dimension is about 10-8 cm. Why is my motivation letter not successful? Rutherford wanted a very thin sheet for his experiment, and gold foil could be pounded into sheets of only 0.00004 cm thickness.

But opting out of some of these cookies may affect your browsing experience. In particular, I wouldn't expect to see a model that predicts concentric wavefunctions for nucleons, the way quantum mechanics describes electrons. A nucleus size is much smaller than the atoms size. A big part of what they do at Jefferson laboratory is to search for the change between nucleon--meson degrees of freedom (as reasonably well described by quantum hadrondynamics) and quark--gluon degrees of freedom (as described by quantum chromodynamics); but even the on-set of QCD dominated behavior does not correspond to quark--gluon plasma which occurs at much higher energies.
