Rev. C 93, 064317. 76Ge; deduced γ-strength function (γSF), nuclear level density (NLD). Comparison to other experimental data and to γ-strength function in 74Ge. 88Br(β-); measured Eγ, Iγ, TAS spectrum using Summing NaI (SuN) detector at Argonne CARIBU facility. 88Kr; deduced γ-strength function (γSF), nuclear level density (NLD). Compared with other experimental data γ-strength functions for 86Kr and 87Kr. 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 87Kr(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.
