High-spin states in the odd-odd nucleus [sup 72]As were investigated by means of coincidence measurements via the [sup 59]Co([sup 19]F,[alpha][ital pn]) and the [sup 65]Cu([sup 12]C,[alpha][ital n]) reactions at beam energies of 55 MeV and 50 MeV, respectively. Two new rotational-like level sequences of probably opposite parities have been found to feed into the known 7[sup ([minus])] isomer at 562.8 keV. Lifetime measurements for some states of the positive-parity sequence using the Doppler shift attenuation method revealed transition strengths of [ital B]([ital E]2)[approx]40 Weisskopf units. Thus, this band is interpreted as a collective structure built on the two-quasiparticle intruder configuration ([pi][ital g][sub 9/2][direct product][nu][ital g][sub 9/2]).
