Excited states in the {sup 99}Pd nucleus populated in the {sup 75}As({sup 28}Si, p3n) fusion-evaporation reaction at E{sub lab}=120 MeV have been investigated through in-beam {gamma}-ray spectroscopic techniques using an array of Compton-suppressed clover detectors. The level scheme is established up to excitation energy {approx}11.5 MeV and spin {approx}25({h_bar}/2{pi}) with the addition of about 60 new transitions. The level structures observed in {sup 99}Pd have been interpreted in the framework of a microscopic theory based on the deformed Hartree-Fock and angular momentum projection techniques. Band structures at lower spins are based on the low-{Omega} {nu}g{sub 7/2} and {nu}d{sub 5/2} orbitals, and those at higher spins are reproduced for the {pi}(g{sub 9/2}){sup 5} x {pi}(g{sub 7/2}) x {nu}(g{sub 7/2}){sup 2} x {nu}(h{sub 11/2}){sup 2} x {nu}(g{sub 9/2}){sup -1} and {pi}(g{sub 9/2}){sup 6} x {nu}(g{sub 9/2}){sup 10} x {nu}(g{sub 7/2}){sup 2} x {nu}(h{sub 11/2}) configurations. The octupole correlations in {sup 99}Pd have been inferred from new interband E1 transitions linking the {Delta}I=1 states of the bands based on the {nu}h{sub 11/2} and {nu}d{sub 5/2} orbitals ({Delta}l=3, {Delta}j=3, and {Delta}{pi}=-1) with the deduced B(E1) values {approx}10{sup -6} W.u.
