Problem 49E

Moderators. ?Canadian nuclear reactors use ?heavy water ?moderators in which elastic collisions occur between the neutrons and deuterons of mass 2.0 u (see Example 8.11 in Section 8.4). (a) What is the speed of a neutron, expressed as a fraction of its original speed, after a head-on, elastic collision with a deuteron that is initially at rest? (b) What is its kinetic energy, expressed as a fraction of its original kinetic energy? (c) How many such successive collisions will reduce the speed of a neutron to 1/59,000 of its original value?

Step-by-Step Solution:

Solution to 49E Step 1 -27 Mass of neutron =1u =1.66x10 kg Mass of deuteron =2u=2.32x10 kg -27 Initial velocity of neutron =2.6x10 m/s 7 Initial velocity of deuteron =0m/s
