As a result of the EUs General Data Protection Regulation (GDPR). Cadmium is a chemical element with symbol Cd and atomic number 48. They're a long way away from being able to actually simulate a whole nucleus. particles are much heavier compared to protons; hence he was expecting them to deflect only slightly by the gold atoms subatomic particles. (b) If atom is represented by planet earth Re=6.4106 m, estimate the size of the nucleus. The mass of the box itself does not affect the energy of the particle inside it: the only thing that matters is the length of the box.

The order of magnitude of the diameter of the earth is (Diameter of the earth is 1.28 10^7 m ). R = R 0 A 1 3 Where R 0 = 1.210 -15 m. From the formula, we can conclude that the volume of the nucleus, which is proportional to R 3, is proportional to A (mass number). The figure of merit for such reactions is $Q^2 = -q \cdot q$, and in the range from about $1$--$8\text{+ GeV}^2$ (the upper limit is not yet experimentally known) the cross-section for this (per target proton) is a constant times the cross-section for the free reaction $p(e,e'p)$.
