<ia>
is the type of interaction,
see following sections.

!target <material>where
<material>
specifies a generic material name
or chemical composition. Targets can be atomic or molecular.
<ia>
={'l,t' | 'x,t' | 'i,t' }
are foreseen for total elastic scattering, excitation, and ionization,
respectively.
!projectile <projectile> !shell <shell-number_1> <E_proj> <sigma_xx/cm**2> [<E_loss>] ... !shell <shell-number_n> <E_proj> <sigma_xx/cm**2> [<E_loss>]Partial cross sections for the different atomic or molecular electronic shells of the target may be given. Use
!shell 0
for the sum of all shells.
<E_proj>
is given in MeV/u for ionic projectiles
and in keV for the others.
<E_loss>
is the potential energy needed for the respective interaction.
It is optional and makes sense for excitations
and for the sum of all shells (!shell 0
).
It is expected in keV.
<ia>
={ 'i,s' }
is foreseen for single (energy) differential ionization,
i.e. secondary electron energy spectra.

Use
!shell 0
if the sum of all shells is given.
<E_proj>
is given in MeV/u for ionic projectiles
and in keV for the others.
<ia>
={ 'l,s' }
is foreseen for elastic scattering angular distributions.

Use
!shell 0
if the sum of all shells is given.
<E_proj>
is given in MeV/u for ionic projectiles
and in keV for the others.
<ia>
={ 'l,d' | 'x,d' | 'i,d' }
is foreseen for double differential (energy,angle) cross sections.
