A systematic study uf the yrast-band structure for the proton-rich, even-ev
en mass-80 nuclei is carried out using the projected shell model approach.
We describe the energy spectra, transition quadrupole moments and gyromagne
tic factors, The observed variations in energy spectra and transition quadr
upole moments in this mass region are discussed in terms of the configurati
on mixing of the projected deformed Nilsson states as a function of shell f
