| Picture including the Cm sample (Al case), the Kapton strip (Kapton), the Mylar foil (Mylar) and the outside aluminum ring (Al ring). The Al ring inner diameter of 7 cm is considerably larger than the beam diameter, which is less than 6 cm. |
| Simulated detector responses (dashed lines with different colors) compared to measured spectra from calibration sources (in black). |
| Experimental gain shift for each detector (Exp.) obtained with the $^{88}$Y measurement as a function of the neutron energy, i.e. time-of-flight. The dashed lines are the fits of each detector response with a logarithmic function. |
| Top panel: Measured counting rate (0.12 $<$ E$\mathrm{_{dep}}$ $<$ 6.0 MeV) as a function of the neutron energy for the Cm sample (Total), together with the beam-on and beam-off backgrounds (see the text for details). The units are counts per pulse and per unit lethargy ($\Delta$LnE, which means that the bin contents have been divided by the natural logarithm of the ratio between the upper and lower bin limits). Bottom panel: measured deposited energy spectra for the first resonance of $^{246}$Cm, between 4.2 and 4.35 eV, together with the beam-on and beam-off backgrounds. |

| Experimental yield (Exp) of the Cm sample together with the partial contribution of the different isotopes ($^{243}$Am, $^{246}$Cm and $^{247}$Cm) calculated with JENDL-4.0. The contribution of the $^{247}$Cm fission yield has been re-scaled to fit the experimental data, thus obtaining $\varepsilon_{fis}$. The black line (Sum) is the sum of the contributions of the different yields. |
| Comparison of experimental and simulated deposited energy spectra of $^{240}$Pu(n,$\gamma$) (0.9 $ |

| Comparison between the simulated deposited energy spectra in the detector due to $^{240}$Pu(n,$\gamma$), $^{246}$Cm(n,$\gamma$) and $^{248}$Cm (n,$\gamma$) cascades. These cascades were used in the analysis. |
| Ratio between the areas of the resonances of the yields obtained with and without the PHWT (i.e. from Eqs. \ref{Eq:yield_WF} and Eq. \ref{Eq:yield_noWF}) for $^{246}$Cm and $^{248}$Cm resonances. The uncertainties of the data are only due to counting statistics. |
| Ratio between the $^{246}$Cm R$\mathrm{_k}$ values obtained in different experiments, including this work, and JENDL-4.0. |
| Experimental capture yield measured in EAR2 for the Cm sample compared with the fitted yields. The experimental capture yield (Exp) includes the uncertainties due to counting statistics only. The green, blue and cyan lines correspond to the capture yield for each isotope. The orange line (BKG) corresponds to the background due to fission and capture events in the actinides. The red line (Sum) corresponds to the sum of all the capture and fission yields. It is important to notice that the resonances in the figures are shifted in energy due to the RF, see Section \ref{sec:Methodology} for more details. |
