Unformatted text preview: to characteristic physical dimensions. Then calculate the de Broglie wavelength for a 10g bullet moving at a speed of 1,000 m/sec. What velocity would the bullet be going if its de Broglie wavelength were 10 − 8 cm? Give the velocity in approximate atomic displacements per year . (You may take 10 − 8 cm. to be the unit of atomic displacements.) 3. Libo f , problem: 7.42 4. A neutron of energy 20 Mev is incident on a square barrier of height 40 Mev and width, 10 F (Fermi). What is the tunneling probability for the neutron to penetrate the barrier? ( You do NOT have to do a complete detailed estimate for this problem. Just estimate the tunneling probability and put in the numbers)....
