      abstract     = {Several experiments have reported anomalies in the neutrino
                      sector which might be explained by the existence of a fourth
                      (sterile) neutrino with a squared mass difference of about 1
                      eV 2 to the other three active neutrinos. The SOX project is
                      part of the experimental program of the Borexino experiment
                      and seeks for a clarification of the observed anomalies. For
                      that purpose an artificial antineutrino source ( 144 Ce−
                      144 Pr) and possibly neutrino source ( 51 Cr) will be
                      deployed underneath the large low background detector
                      Borexino. The detector pro- vides both energy and vertex
                      resolution to observe a possible oscillation signature
                      within the detector volume. The calculation of the
                      antineutrino spectrum is based on existing theoreti- cal
                      models and was performed within this thesis. The modeling
                      includes several sub-leading corrections particularly such
                      as finite size of the nucleus, screening of the atomic
                      electrons and radiative effects. Related to this work,
                      dedicated Monte Carlo generators have been de- veloped to
                      simulate the inverse beta decay reaction and the
                      (anti)neutrino elastic scattering off electrons. Based on a
                      profile likelihood analysis, the sensitivity to the sterile
                      neutrino search of the SOX project was evaluated. The
                      results obtained from this analysis confirm that the
                      currently allowed parameter regions for sterile neutrinos
                      can be tested at $95\%$ confi- dence level. Finally, an
                      alternative concept for the sterile neutrino search is
                      presented which is based on a cyclotron and a Beryllium
                      target near Borexino (Borexino+IsoDAR).},
