MnF_(2) has a tetragonal crystal structure in which the Mn ions are situated at the corners of the tetragonal unit cell a=b=0.5nm and c=0.3nm, and at the body-centred position in the unit cell. Below 70K the spins of the Mn ions become antiferromagnetically aligned along the c axis with the spins of an ion at the centre of the unit cell aligned opposite to those at the corners. The neutron scattering from a powdered sample of MnF_(2) is measured using an incident neutron wavelength of 0.3nm and an angle of scattering between 0^(@) and 90^(@). Sketch the results you would expect to observe at (a) 100K and (b) 10K. You can neglect the scattering from the F ions.
