Abstract.
High-spin states in 79Rb were populated in the reaction \(\mathrm{^{63}Cu \ensuremath(^{19}F, p2n) ^{79}Rb}\) at E(beam) = 60 MeV. The lifetimes of the excited states of the \(\pi \ensuremath g_{\frac{9}{2}}\) positive-parity yrast band and of the \(\pi \ensuremath p_{\frac{3}{2}}\) negative-parity band in 79Rb were measured by the Doppler Shift Attenuation Method. The deduced transition quadrupole moments Qt are found to have a decreasing trend with rotational frequency for both the bands, consistent with those found experimentally in neighbouring nuclei.
