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