Proton and neutron alignments in negative-parity bands of ${}_{}{}^{76}{}_{}{}^{}\mathrm{Kr}$

High-spin states in ${}_{}{}^{76}{}_{}{}^{}\mathrm{Kr}$ were studied using the ${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$${(}^{28}$Si, α 2p) reaction at 120 MeV. Two new level sequences with negative parity decaying to known states in ${}_{}{}^{76}{}_{}{}^{}\mathrm{Kr}$ have been identified from prompt γ-γ coincidences. The observed band crossings at a rotational frequency of about 0.55 MeV/ħ can be understood as a ${\mathit{g}}_{9/2}$ quasiproton alignment in bands built on two-quasineutron excitations at near-prolate deformation, in contrast to the ${\mathit{g}}_{9/2}$ quasineutron alignment at about 0.75 MeV/ħ in the previously known two-quasiproton negative-parity bands.
