  Using intrinsic multiple Andreev reflections effect (IMARE) spectroscopy, we
studied ballistic superconductor - normal metal - superconductor (SnS) contacts
in layered oxypnictide superconductors NdFeAsO$_{0.6}$H$_{0.36}$ with critical
temperatures $T_c = 45-48$ K. We directly determined the magnitude of two bulk
superconducting order parameters, the large gap $\Delta_L \approx 10.4$ meV,
and a possible small gap $\Delta_S \approx 1.8$ meV, and their temperature
dependence. Additionally, a resonant coupling with a characteristic bosonic
mode was observed. The boson energy at 4.2 K, $\varepsilon_0 = 10.5-11.0$ meV
being less than the indirect gap ($\Delta_L < \varepsilon_0 < \Delta_L
+\Delta_S$).
