High-spin states in <sup>70,72</sup>Se have been extended up to spin 14<sup>+</sup> and 28<sup>+</sup>, respectively. The yrast bands in both nuclei exhibit a very regular rotational pattern up to the highest spins observed, with no indication of band crossings above hw approximately=0.5 MeV. According to deformed shell modeling calculations the regular yrast structures can be associated with aligned configurations involving g<sub>9/2</sub> quasiparticles.
