$l=1$ strength functions for ${}^{92,94,96,98}$Mo (a)–(d) as a function of energy $E\equiv E_{\gamma }$. Thick red curves refer to strength functions calculated using the GLO model, green dotted curves to strength functions from the SLO model and pink dotted curves are from non-smoker, calculated with the DLO. The black points are experimental data, with error bars shown. Solid black curves refer to the TLO calculations, and provide an estimate of the strength function in the energy region of 0 to 4.5 MeV. Thin red curves represent the $M1$ strength function. Red points illustrate the strength function for discrete states in the compound nucleus. For $E<4$ MeV, in panels (a) and (d) the red points are from Ref. [36], in panel (b) they are from Ref. [33] and in panel (c) they are from Ref. [34]. Where applicable, above 4 MeV red points are from Ref. [14]. The ones in panel (d) are additionally from Ref. [15]. For $4.5\lesssim E\lesssim S_n$ black data points are from Refs. [14] [in panels (a)–(c)] and [15] [in panel (d)]. For all panels, black data points in the region $S_n\lesssim E$ are from Ref. [40] with corrections described in the text. The arrows depict the neutron separation energies $S_n$.Reuse & Permissions
