Improved Pt() and Ir() astrophysical reactions rates
P. E. Koehler, K. H. Guber
Pt is produced solely by the slow neutron capture (\textit{s}) nucleosynthesis process and hence an accurate (,) reaction rate for this nuclide would allow its use as…
Neutron Resonance Data Exclude Random Matrix Theory
P. E. Koehler, F. Bečvář, M. Krtička +2
Almost since the time it was formulated, the overwhelming consensus has been that random matrix theory (RMT) is in excellent agreement with neutron resonance data. However, over th…
Anomalous fluctuations of s-wave reduced neutron widths of Pt resonances
P. E. Koehler, F. Bečvář, M. Krtička +2
We obtained an unprecedentedly large number of s-wave neutron widths through R-matrix analysis of neutron cross-section measurements on enriched Pt samples. Careful analysis of the…
Non-Statistical Effects in Neutron Capture
P. E. Koehler, T. A. Bredeweg, K. H. Guber +8
There have been many reports of non-statistical effects in neutron-capture measurements. However, reports of deviations of reduced-neutron-width distributions from the expected Por…
