Neutron's crow flight distance & 2° moment of a distribution

[QUOTE="dRic2, post: 6147528, member: 638830"] Hi, I'm looking for a simple explanation of the meaning of the crow flight distance and why it is defined as the second moment of a probability distribution: $$\bar r^2 = \int r^2 p(r)dr$$ Where ##p(r)## is the probability that a neutron is absorbed in the interval ##dr## near ##r##. And what exactly is the meaning of the second moment of a probability distribution ? Thanks Ric [/QUOTE]
