Rev. C 93, 064317. ^{76}Ge; deduced γ-strength function (γSF), nuclear level density (NLD). Comparison to other experimental data and to γ-strength function in ^{74}Ge. ^{88}Br(β^{-}); measured Eγ, Iγ, TAS spectrum using Summing NaI (SuN) detector at Argonne CARIBU facility. ^{88}Kr; deduced γ-strength function (γSF), nuclear level density (NLD). Compared with other experimental data γ-strength functions for ^{86}Kr and ^{87}Kr. NLD results are compared to calculations done with 3 semi-microscopic models - HFB+Skyrme, HFB+Skyrme combinatorial, temperature-dependent HFB+Gogny. Combination of "shape" method with β-Oslo technique which allows extraction of NLD in model independent way. NUCLEAR REACTIONS ^{87}Kr(n, γ), E<1 MeV; calculated σ(E) using newly obtained NLD. Values are given relative to calculated ones using current RIPL-3 recommended level densities.
