Alpha-particle scattering experiments using uranium (Z = 92) as the target material
show that the alpha-particles experience a pure Coulomb repulsion only for energies up to 8.8 MeV. Estimate the radius of the uranium nucleus.

In Rutherford's scattering experiments, alpha particles (charge = +2e) were fired at a gold foil. Consider an alpha particle with an initial kinetic energy K heading directly for the nucleus of a gold atom (charge =+79e). The alpha particle will come to rest when all its initial kinetic energy has been converted to electrical potential energy. Find the distance of closest approach between the alpha particle and the gold nucleus for the case K = 3.5 MeV

In Rutherford's famous scattering experiments that led to the planetary model of the atom, alpha particles (having charges of +2e and masses of 6.64 × 10-27 kg) were fired toward a gold nucleus with charge +79e. An alpha particle, initially very far from the gold nucleus, is fired at 2.60 × 10' m/s directly toward the nucleus, as in the figure below How close does the alpha particle get to the gold nucleus before turning around? Assume the gold nucleus...

1. (a) Calculate the potential energy of an alpha particle (z= 2. A = 4) just touching a nucleus of gold (z= 79, A = 178) (b) Would you expect the scattering of 18 MeV alpha particles on gold to obey the Rutherford scattering law?
Using the steps outlined below, calculate the distance of closest approach when alpha particles with a kinetic energy of 8.1 MeV are scattered by a thin zinc foil. a.What should be the arrangement of the particles for the alpha particle to get as close as possible to the zinc nucleus? (Head on or glancing inter action?) b. Write an expression for the electrostatic potential energy of a system consisting of an alpha particle and a zinc nucleus.This should be a...
The Heidelberger Ionenstrahl-Therapiezentrum (HIT) has a particle accelerator capable of reaching beam kinetic energies of 500 MeV per nucleon. Instead of using protons or alpha particles, Dr. X wants to investigate the effects of high LET radiation in a tissue irradiation experiment with a 12C (A=12, Z=6) ion beam with a kinetic energy of 6000 MeV. The carbon ion beam (stripped of electrons) will be impinging on a radially symmetric (e.g. cylindrical) tissue-equivalent target. Using the Bethe-Bloch equation, calculate the...

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
