[@Mo_RSF], and to $\rho(S_n) = 1.90(95) \times 10^5$ MeV$^{-1}$ following [@go08]. It is seen that both normalizations reproduce well the known, discrete levels taken from [@ENSDF]. In Fig. \[fig01\] the corresponding RSFs for both normalizations are displayed, and it is seen how the slope of the RSFs is changed. Note that for both cases the total RSF is normalized in absolute value to the average total radiative width $\left< \Gamma_{\gamma}(S_n) \right>$. For the cases of $^{93,95,97,98}$Mo the upbend structure is clearly present and relatively strong, for both normalizations of the NLD, while for $^{94,96}$Mo the enhancement is reduced. However, this new normalization does not question the presence of the upbend in the RSF.

In summary, the Oslo method has now been widely tested to confirm its capacity to determine the NLD and RSF. It has proven to be an excellent procedure and there is, at present, no reason not to trust the low-energy RSF data showing an upbend pattern. For that reason, we will now assume that this structure is present in all elements lighter than typically Cd (no upbend has been seen in Sn isotopes [@Sn]), and discuss how it can be modeled as an $E1$ strength.
