  The cosmogenic neutron yield $Y_n$ characterizes the matter ability to
produce neutrons under the effect of cosmic ray muons with spectrum and average
energy corresponding to an observation depth. The yield is the basic
characteristic of cosmogenic neutrons. The neutron production rate and neutron
flux both are derivatives of the yield. The constancy of the exponents $\alpha$
and $\beta$ in the known dependences of the yield on energy $Y_n {\propto}
E_{\mu}^\alpha$ and the atomic weight $Y_n {\propto} A^\beta$ allows to combine
these dependences in a single formula and to connect the yield with muon energy
loss in the matter. As a result, the phenomenological formulas for the yield of
muon-induced charged pions and neutrons can be obtained. These expressions both
are associated with nuclear loss of the ultrarelativistic muons, which provides
the main contribution to the total neutron yield. The total yield can be
described by a universal formula, which is the best fit of experimental data.
