Abstract: 
Face to face collision of ion acoustic multi-solitons is studied for the electron-positron-ion plasma with nonthermal non-extensive electrons using extended version of Poincare-Lighhill-Kuo (PLK) method. Three soliton expressions have been derived by Hirota’s method. It is observed that there is a phase shift in each soliton due to collision. The change in phase shift is studied with nonthermal non-extensive parameter q in the range . It has been seen that the nonthermal non-extensive parameter plays a significant role on phase shift.
