Presently there is a great deal of interest to experimentally observe neutrinoless double beta (0νββ) decays. This exotic decay mode can only be observed in a few isotopes over the nuclear chart. An observation of 0νββ decay would signify physics beyond the standard model and the decay rate can be used to determine the absolute scale of neutrino masses. A major difficulty in extracting the effective neutrino mass from the decay lifetime arises from the uncertainties associated with the matrix element calculated for the decay. One of the most promising candidate for observing this decay mode is the decay of <sup>136</sup>Xe to <sup>136</sup>Ba. There are several experiments planned world-wide to observe the 0νββ in <sup>136</sup>Xe. In this talk I present preliminary results from the <sup>138</sup>Ba(d,a) reaction used to study low lying excited states in <sup>136</sup>Cs, which is the intermediate nucleus in <sup>136</sup>Xe 0νββ decay. I will also discuss future plans to study neutron pairing in the daughter <sup>136</sup>Ba nucleus via the <sup>138</sup>Ba(p,t) reaction using the same approach. Our results will provide useful spectroscopic information for the matrix element calculations in this mass region.
