We study the spin-parity distribution P(J$^{\pi}$,E) of $^{156}$Gd excitedstates above the neutron separation energy that are expected to be populatedvia the neutron pickup reaction $^{157}$Gd($^{3}$He,$^{4}$He)$^{156}$Gd. Ingeneral, modeling of the spin-parity distribution is important for theapplicability of the surrogate reaction technique as a method of deducingreaction cross sections. We model excited states in $^{156}$Gd as rotationalstates built on intrinsic states consisting of a hole in the core where thehole represents neutron removal form a deformed single particle state. Thereaction cross section to each excited state is calculated using standardreaction code that uses spherical reaction form-factor input. The spectroscopicfactor associated with each form-factor is the expansion coefficient of thedeformed neutron state in a spherical Sturmian basis consisting of thespherical reaction form-factors.
