<strong>The</strong> electron would <strong>the</strong>refore leave a trail <strong>of</strong> deflected ions<br />
behind it. This trail that extends for a distance l, and only<br />
exists along a narrow tube in between ions.<br />
This net positive charge can attraction ano<strong>the</strong>r electron that<br />
happens to be travelling in <strong>the</strong> opposite direction through this<br />
same tube.<br />
So <strong>the</strong>re is an attractive potential between two such electrons<br />
that extends over <strong>the</strong> distance l.<br />
