NUCLEAR STRUCTURE ⁵⁴Cr, ¹⁰⁰Ru, ¹³⁰Xe, ¹⁸⁰Hf, ²⁰⁸Pb, ²³⁸U; calculated excitation energies, quadrupole deformations, moments of inertia as function of nuclear temperature. A=20-250; deduced ratio of HFB plus combinatorial densities to experimental s-wave neutron resonance spacings as function of temperature. ⁴⁰Ca, ⁴²K, ^50,51V, ^56,57Fe, ⁵⁸Ni, ⁶⁰Co, ⁶⁸Zn, ⁹⁰Zr, ^90,94Nb, ^{93,94,95,96,97,98}Mo, ¹⁰⁷Cd, ¹²⁷Te, ¹³²Xe, ^148,149Sm, ¹⁵⁵Eu, ^160,161,162Dy, ^166,167,168Er, ^171,172Yb, ¹⁷⁸Hf, ¹⁹⁴Ir, ²⁰⁸Pb, ²¹⁰Bi, ²³⁷U, ²³⁸U, ²³⁸Np, ²³⁹Pu, ²⁴²Am; calculated combinatorial nuclear level densities (NLD) using temperature-dependent D1M Gogny interaction. Comparison with experimental data. Z=50, N=50-120; deduced ratio of Maxwellian-averaged (n, γ) rates for T₉=1 obtained with current NLDs and those in previous calculations.
