Reply from Pakzad

Abstract

The main point in Verheest & Pillay’s “Comment on Dust acoustic solitary waves in dusty plasma with nonthermal ions”, against my article which appeared in Astrophys. Space Sci. 324, 41–45 (2009) is that the authors had published a more complete article than the above manuscript about a year and a half earlier. They conclude that Pakzad did not survey the mainstream literature before publishing the manuscript. Here are some suggestions which may help authors to revise their opinion. A short examination of the previous articles by Pakzad reveals that the above manuscript is a natural expansion of his previous works. The paper mainly deals with the conditions for the existence of solitary waves in a medium containing nonthermal electrons. As stated in this manuscript, this point is widely applicable—independent of the double layer situation which has been investigated in the nice work of Verheest and collaborators. In fact Pakzad’s work is both parallel to (and also independent of) the very complete work presented by Verheest et al. The referee for our paper considered this point in his/her final decision. To find both parallel and independent works is not surprising news in view of the recent situation of knowledge and specially in plasma physics. One can find that all the articles cited below have investigated the same problems as Verheest both before and after their work.
