We have studied the phenomenon of solitary wave formation in a relativistic plasma
having both positive and negative ions. The state of the plasma is assumed to be
isothermal and ions are considered to be warm. The phase velocity, width and amplitude of
the soliton are explicitly obtained as functions of sa,
sb, nb0/na0, ua0/c, ub0/c and Q, where sa and sb are the temperatures of the two kinds of ions, na0 and nb0 are the
respective equilibrium densities, ua0 and ub0 are the corresponding streaming velocities and Q is the mass
ratio of the negative and positive ions.
