Cylindrical and spherical solitons in a positive-ion–negative-ion plasma

Abstract

Experiments on the excitation of cylindrical and spherical solitons in a positive-ion--negative-ion--electron plasma are described. The results are in substantial agreement with the theoretical model proposed by Das and Singh [Aust. J. Phys. 44, 523 (1991)]. In addition, experiments on the oblique collision of solitons in a cylindrical geometry are described.
