1. The problem statement, all variables and given/known data

Given variables and data: flux of alpha particles;Z; T-kinetic energy of the flux;
t-thickness of the target.I have to calculate the number of alpha particles which are
scattered in angle θ>60 degrees.
2. Relevant equations

1) Is my formula correct ( see below) if Im including the T-kinetic energy ?
2) Do i have to integrate the solid angle element dΩ from 60 to 360 degrees?
3) What kind of value should I put in the sin^4(θ/2)- do I have to integrate this part as well ?

3. The attempt at a solution
dN/N=n ((Ze^2)/(8 Pi ε T))^2 dΩ/(sin^4(θ/2))
Where θ-scattering angle
ε-electric constant
n-atoms per unit volume in target
e-electron charge
