Telah dilakukan perhitungan pergeseran fase hamburan Pion Nukleon untuk gelombang parsial S; P dan D, dan untuk isospin 1, 2 dan 32 . Interaksi menggunakan bentuk separabel rank-1 dan rank-2. Parameter interaksi ditentukan melalui fittting dengan data pergeseran fase analisis SAID. Didapatkan bahwa rank-1 dan rank-2 dapat memfit data dengan baik sampai momentum 400 MeV/c. Disamping itu, rank -2 dapat menjelaskan cukup baik sampai momentum 1200 MeV/c.

Phaseshift of Pion-Nucleon Scattering has been calculated for the partial waves

S; P, and D, and for the isospin 1,2 and 3

2 . The interaction is assumed to take the separable form of rank-1 and rank-2. Interaction parameters are determined through fitting with the phaseshift data of SAID analysis. It is found that the rank-1 and rank-2 can fit the data quite well for the momentum up to 400 MeV/c. Meanwhile, the rank-2 can describe the data fairly well for the momentum up to 1200 MeV/c.
