as a function of both LAB and COM.

Problem 13

Use the diagram showing neutron velocity before and after a collision
to conclude that:

where a = [(A – 1)/(A + 1)]2
is known as the collision parameter. Use this relation to:

a) find the angle corresponding to the minimum energy of the
emerging neutron ( E_min  )

b) find E_min, the minimum
energy of the emerging neutron
