High angular momentum states in [sup 79]Rb were populated via the [sup 63]Cu([sup 19]F,2[ital pn])[sup 79]Rb and [sup 65]Cu([sup 18]O,4[ital n])[sup 79]Rb reactions. The 65 MeV [sup 19]F and 65 MeV [sup 18]O beams were provided by the Florida State University FN Tandem accelerator. Prompt [gamma]-[gamma] coincidences were measured for both reactions. Two additional [gamma] cascades have been assigned to [sup 79]Rb, including a new high-excitation structure dominated by dipole transitions. Firm spin assignments were made for the first time for a number of states by means of directional correlation ratios and an angular distribution measurement using the [sup 63]Cu([sup 19]F,2[ital pn]) reaction. The Doppler-shift attenuation method was used to determine lifetimes for states and their respective side-feeding times in both the yrast positive-parity and yrast negative-parity states. Transition quadrupole moments were deduced from the transition strengths and compared with those predicted by Woods-Saxon cranking calculations. The energy spacings and mixing ratios were compared with particle-rotor calculations.
