    Yes, the microscopic cross-section σ has units of area.

    The differential cross-section is a measure of how the microscopic cross-section, σ, changes with respect to the solid angle, Ω.

    I am sure that there is a c = 1 or a hbar = 1 in this formula which disables one to do dimesional calculus.
    Do you know how this equality is deduced?
