摘要
Ion-acoustic solitary waves in the negative ion plasmas in the presence of generalized (r , q) distributed electrons are studied. Equations of states for positive and negative ions are included in magnetized plasma. Reductive perturbation method (RPM) are applied to derive the Zakharov-Kuznetsov (ZK) equation. The impact of variation of spectral indices on propagation characteristic of ion acoustic solitary waves in negative ion plasma is discussed. The effect of negative ion temperature in the presence of generalized distribution of electrons is also presented. Our findings predict that equation of state of negative ions affects amplitude and width of the nonlinear solitary structure significantly. Our findings are applicable to laboratory as well as space plasmas where negative ion plasmas exist with magnetic field, and a flat-top feature for low-energy electrons and a high-energy tail in the distribution function of the electrons have been observed.
