FE²�?ZNS CRYSTAL NO FURTHER A MYSTERY

Satellite peak one, which has a binding Power of 716.1 eV, offers very clear proof for your existence of Fe2+. Satellite peak 2, with a binding Strength of 720.1 eV, might be assigned to the attribute peaks of Fe3+; its peak depth is rather weak in contrast with satellite peak 1, which indicates that the amount of Fe3+ is extremely modest in the ir
