A proton and a deuteron (which has the same charge as the proton but 2.0 times the mass) are incident on a barrier of thickness 10.5 fm and “height” 11.1 MeV. Each particle has a kinetic energy of 2.80 MeV.


a.) Which particle has the higher probability of tunneling through the barrier?

   a. Photon

   b. none of them will pass through the   barrier

   c. both have same probability


b. What is the ratio of the tunneling probability of the proton to the tunneling probability of the deuteron?

An alpha particle is a nucleus of helium-4. It has twice the charge and four times the mass of the proton. An alpha particle and a proton are initially at rest a distance of 2.0 × 10^-13 m from each other. After they are released, what are their velocities when they are very far from each other?  Hint: There are two conserved quantities. Make use of both of them. (c = 3.00 × 10^8 m/s, k = 9.0 × 10^9 N...

An alpha particle (α), which is the same as a helium-4 nucleus, is momentarily at rest in a region of space occupied by an electric field. The particle then begins to move. Find the speed of the alpha particle after it has moved through a potential difference of −3.45×10−3 V .The charge and the mass of an alpha particle are qα = 3.20×10−19 C and mα = 6.68×10−27 kg , respectively.
