{sup 30}P has been studied by in-beam {gamma}-spectroscopy following the fusion-evaporation reaction {sup 16}O({sup 16}O,pn) at E{sub lab}=40 MeV, using the Indian National Gamma (Clover) Array (INGA) up to moderate spins (I=5). Polarization measurements of seven gamma rays have been performed for the first time. To understand the underlying structure of the levels and transition mechanisms, experimental data have been compared with the results from large basis cross-shell shell model calculations. The results for the negative parity states are especially important in this respect. Positive parity states indicate an onset of collectivity, whereas the negative parity states are members of {nu}-{pi} multiplets.
