We present intersection type systems in the style of sequent calculus,modifying the systems that Valentini introduced to prove normalisationproperties without using the reducibility method. Our systems are more naturalthan Valentini's ones and equivalent to the usual natural deduction stylesystems. We prove the characterisation theorems of strong and weaknormalisation through the proposed systems, and, moreover, the approximationtheorem by means of direct inductive arguments. This provides in a uniform wayproofs of the normalisation and approximation theorems via type systems insequent calculus style.
