We have a spin-one-half projectile (mass m, Energy E = ℎ 2

2

ଶ

). This projectile scatters

a spin-one-target of infinite mass.

For this, the Hamiltonian is:

∫ = ଵଶ

−

In the above expression, µ > 0, σi represent the Pauli spin operators, where for i=1,

we have the spin operator for projectile and for i=2, we have spin operator for

target.

(differential scattering cross section), in lowest order Born

approximation. The same should be calculated as a function of k and scattering

angle. Also, computation should be done averaging over initial; and summing over

final states of spin polarization.​
