Description
We explore the neutrinos from decays of stopped atmospheric muons in
the Earth. In terms of the atmospheric muon flux at the sea-level
and the average muon range $R$, we derive the depth distribution of
stopped muons in the Earth. The stopped $\mu^-$ can be captured by
different nuclei in the rock. Based on the mean-life of captured
$\mu^-$ and the average muonic capture probabilities of different
elements, we find that about 60% stopped $\mu^-$ can decay and
produce the low energy neutrinos (< 53 MeV). Then we calculate the
$\nu_e$, $\bar{\nu}_e$, $\nu_\mu$ and $\bar{\nu}_\mu$ fluxes from
all stopped $\mu^+$ and $\mu^-$ in the Earth, which have about
10%, 6%, 3% and 7% of the corresponding atmospheric
neutrino fluxes. The new neutrino source is very helpful for us to
investigate the diffuse supernova neutrinos and some related topics.
