The neutron capture cross section for $^{ 90}Zr(n, \gamma)$ has recently been determined using surrogate $^{ 92}Zr(p, d\gamma)$ data and nuclear reaction theory. That work employed an approximate fitting method based on Bayesian Monte Carlo sampling to determine parameters needed for calculating the $^{ 90}Zr(n, \gamma)$ cross section. Here, we improve the approach by introducing a more sophisticated Markov Chain Monte Carlo sampling method. We present preliminary results.
