&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The typical time of permanence of a particle in a given environment.&lt;br /&gt;
More precisely, the decay time &amp;lt;math&amp;gt;\tau&amp;lt;/math&amp;gt; that appears&lt;br /&gt;
in the exponential decay &amp;lt;math&amp;gt;\exp(-t/\tau)&amp;lt;/math&amp;gt; at long times.&lt;br /&gt;
Historically, the concept was introduced to describe the time&lt;br /&gt;
a particle is close to another [1], but it can be employed&lt;br /&gt;
in other situations, as in [[Diffusion_at_interfaces | diffusion&lt;br /&gt;
at interfaces]].&lt;br /&gt;
