PROBLEM 2: Consider neutrons slowing down by elastic scattering from 1.0 MeV to 0.025 eV
in large spatially homogeneous regions.
(a) Estimate the number of scattering events required for these neutrons to slow down in large
regions of hydrogen (A = 1), iron (A = 56), and uranium (A = 238).
(b) Suppose that in each neutron-nucleus collision, the probability that a neutron is captured
is 0.001 (independent of energy). Estimate the probability that these neutrons in regions
238) will not be captured while
of hydrogen (A
1), iron (A
56), and uranium (A
slowing down from 1.0 MeV to 0.025 e V.
Note: In practice, the probability that a neutron with energy E will be captured depends on E.
This makes realistic calculations of the non-capture probability considerably more difficult.
An alpha particle with kinetic energy 11.0 MeV
makes a collision with lead nucleus, but it is not
"aimed" at the center of the lead nucleus, and has
an initial nonzero angular momentum (with respect
to the stationary lead nucleus) of magnitude
L=pob, where po is the magnitude of the initial
momentum of the alpha particle and

The mass difference between two isotopes is sometimes just a neutron mass. The spectrometer should separate them very well. For such an isotope combination, the difference in radius should be around 1 cm. That is r, – r, = 1 cm. In order to achieve this, choose a magnetic field with a magnitude in Tesla (maximum magnetic field you can obtain from a conventional magnet is around 2.5 T so be far away from this value) and choose the direction also. Then determine the velocity of isotope you need. Last calculate radius r of a Pb04 smallest isotope. 2.
