The possibility of wobbling mode in the A 80 mass region is investigated by using the constrained triaxial covariant density functional theory and quantum particle rotor model for rubidium isotopes. Several states with the obvious triaxial deformation and high-j particle configuration are obtained in
Rb, which are suitable for establishing the wobbling mode. Taking the nucleus
Rb as an example, the available experimental energy spectrum with the
g
configuration is described well. The decreased energy difference between the partner bands, the enhanced
/
values, the angular momentum components and the azimuthal plots indicate that
Rb can be transverse wobbling candidate. The present work provides a promising basis for future experimental research on the wobbling mode in the A
80 mass region.
