In a Rutherford scattering experiment, an α-particle (charge = +2e) heads directly toward a lead nucleus (charge = +82e). The α-particle had a kinetic energy of 4.5 MeV when very far (r → ∞) from the nucleus. Assuming the lead nucleus to be fixed in space, determine the distance of closest approach (in fm).

1: The radioactive decay of heavy nuclei by emissions of an alpha particle is a result of quantum tunneling. Imagine an alpha particle moving around inside a nucleus, approximated by a 1D potential well. When the alpha bounces against the surface of the nucleus, it meets a barrier caused by the attractive nuclear strong force. The dimensions of this barrier vary a lot from one nucleus to another, but as representative numbers you can assume that the barrier’s width is...

Consider a particle trapped in an infinite square well potential of length L. The energy states of such a particle are given by the formula: En=n^2ℏ^2π^2 /(2mL^2 ) where m is the mass of the particle. (a)By considering the change in energy of the particle as the length of the well changes calculate the force required to contain the particle. [Hint: dE=Fdx] (b)Consider the case of a hydrogen atom. This can be modeled as an electron trapped in an infinite...

Each alpha particle in a beam of alpha particles has a kinetic energy of 5.0 MeV. Through what potential difference would you have to accelerate these alpha particles in order that they would have enough energy so that if one is fired head-on at a gold nucleus it could reach a point 1.0x10^-14 m from the center of the nucleus? I know that the answer is delta V = 9e6 Volts I am struggling to get past KEi = 5.0...
