  Existence of hypothetical fourth neutrino, so-called sterile neutrino, is one
of open issues in the particle and neutrino physics. This fourth neutrino is a
candidate for explaining some anomalies reported in LSND, MiniBoone, reactor
experiments, and gallium experiments. To search for the existence of the
sterile neutrino, we report detailed analysis of a feasible experiment for
short baseline electron antineutrino (${\bar{\nu}}_{e}$) disappearance study,
in which a ${\bar{\nu}}_{e}$ source from $^{8}$Li generator is considered under
non-accelerator system. For $^{8}$Li production, we suggest to use $^{252}$Cf
source as an intense neutron emitter, by which one can produce $^{8}$Li isotope
through $^{7}$Li(n,$\gamma$)$^{8}$Li reaction, effectively. Using the $^{8}$Li
generator, one does not need any accelerator or reactor facilities because the
generator can be placed on any present and/or planned neutrino detectors as
closely as possible. For the effect of the possible sterile neutrinos, we
estimate expected neutrino flux and event rates from the neutrino source
scheme, and show neutrino disappearance features and possible reaction rate
changes by the sterile neutrino using the spectral shape analysis.
