  Photon strength, $f(E_{\gamma})$, measured in photonuclear reactions, is the
product of the average level density per MeV, $\rho(E_x)$, and the average
reduced level width, $\Gamma_{\gamma}/E_{\gamma}^3$ for levels populated
primarily by E1 transitions at an excitation energy $E_x=E_{\gamma}$. It can be
calculated with the Brink-Axel (BA) formulation modified to include
contributions from the Giant Dipole Resonance (GDR) and higher lying
resonances. Level densities and reduced widths have been calculated for 17
nuclei with atomic numbers between Z=14-92. Level densities below the GDR
energy were calculated with the CT-JPI model and combined with the BA photon
strength to determine the associated reduced widths. The reduced widths varied
exponentially with level energy and could be extrapolated up to higher
energies. The extrapolated widths were then combined with the BA photon
strength to determine the level densities at higher energies. The level
densities are found to increase exponentially at low energies, peak near the
GDR energy due to the appearance of new states at the $2\hbar\omega$ shell
closure, and continue to increase less rapidly up to at least 30 MeV. The
average level densities have been compared with the Fermi Gas Level Density
(FGLD), Back-Shifted Fermi Gas (BSFG), and Hartree-Fock-Bogoliubov (HFB)
models. Good agreement is found with the nearly identical FGLD and BDFG models,
while the HFB models gives substantially lower level densities. A universal set
of FGLD model parameters were determined as a function of mass and temperature
that are applicable to all nuclei.
