Abstract
The neutron capture cross section for 90 Zr(n, γ) has recently been determined using surrogate 92 Zr(p, dγ) data and nuclear reaction theory (J.E. Escher et al., Phys Rev Lett 121:052501, 2018). That work employed an approximate fitting method based on Bayesian Monte Carlo sampling to determine parameters needed for calculating the 90 Zr(n, γ) cross section. Here, we improve the approach by introducing a more sophisticated Markov-Chain Monte Carlo sampling method (W.K. Hastings, Biometrika 57:97, 1970). We present preliminary results.
