1. Suppose that during an inelastic scattering collision the target nucleus absorbs an amount of energy Q. Show that: EE=(1+A)2A2+1+2Acos() becomes EE=(1+A)2A22+1+2Acos() Where =1EQ1+AA 2. Show that the expression for the average loss in the logarithm of the energy during a collision =1+1Ln() may be approximated by =A+322forlargeA,where:=(A+1A1)2. Hint: Let =1 and B=A1, then do a series expansion
