Text Solution

AI Generated Solution

To solve the problem of calculating the energy transferred from a neutron to a beryllium nucleus during an elastic head-on collision, we can follow these steps: ### Step-by-Step Solution: 1. **Define Variables:** - Let the mass of the neutron be \( m \). - The mass of beryllium (mass number = 8) is \( 8m \). - Let the initial velocity of the neutron be \( u \) and the initial velocity of beryllium be \( 0 \) (since it is at rest). ...

consider an elastic collision between a neutron and a light particle like carbon and calculate fractional KE lost.

As part of his discovery of the neutron in 1932, James Chadwick determined the mass of the neutron (newly identified particle) by firing a beam of fast meutrons, all having the same speed, as two different targets and measuing the maximum recoil speeds of the target nuclei. The maximum speed arise when an elastic head-on collision occurs between a neutron and a stationary target nucleus. Represent the masses and final speeds of the two target nuclei as m_(1), v_(1), m_(2) and v_(2) and assume Newtonian mechanics applies. The neutron mass can be calculated from the equation: m_(n) = (m_(1)v_(1) - m_(2)v_(2))/(v_(2) - v_(1)) Chadwick directed a beam of neutrons on paraffin, which contains hydrogen. The maximum speed of the protons ejected was found to be 3.3 xx 10^(7) m//s . A second experiment was performed using neutrons from the same source and nitrogen nuclei as the target. The maximum recoil speed of the nitrogen nuclei was found to be 4.7 xx 10^(6) m//s . The masses of a proton and a nitrogen nucleus were taken as 1u and 14 u , respectively. What was Chadwick's value for the neutron mass?

A neutron collides, head-on with a deuterium at rest. What fraction of the neutron's energy would be transferred to the deuterium?

In a nuclear reactor, a neutron of high speed (~~10^(7)ms^(-1)) must be slowed down to 10^(3)ms^(-1) so that it can have a high probality of interacting with isotipe _92U^(235) and causing it to fission. Show that a neutron can lose most of its K.E. in an elastic collision with a light nuclei like deuterium or carbon which has a mass of only a fewe times the neutron mass. The material making up the light nuclei usually heavy water (D_(2)O) or graphite is called modertaor.
