MENDOZA-BRICENO, C. A  e  LUNA-CARDOZO, M. Estructuras solitarias de amplitud arbitraria en plasmas a dos temperaturas electrónicas con iones fríos. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.230-232. ISSN 0035-001X.

The compresive and rarefactive ion-acoustic solitary wave of arbitrary amplitude which have been found to coexist in two-electron temperature plasmas, are investigated by the pseudo potential approach. An expression of this pseudo potential have been derived and the range of the parameters space M_s, α and µ for the coexistence of these solitary structures are found for the case of cold ion plasma. Aditionally, the effect of the parameters space on wave amplitude was studied.
