摘要: Ion-acoustic (IA) solitary wave propagation is investigated by solving the fractional Schamel equation (FSE) in a homogenous system of unmagnetized plasma. This plasma consists nonextensive trapped electrons and cold fluid ions. The effects q-parameter, electron trapping, parameter have been studied. FSE derived using semi-inverse Agrawal's methods. analytical results show that an increase amount trapping q-parameter increases soliton ion-acoustic amplitude agreement with previously obtained results. However, it vice-versa for parameter. feature leads to fact may be used IA instead increasing parameters.
