We present the results of a calculation of the beta-decay half-lives of several proton-rich even-even nuclei of intermediate mass: ${}_{}{}^{74}{}_{}{}^{}\mathrm{Sr}$, ${}_{}{}^{76}{}_{}{}^{}\mathrm{Sr}$, ${}_{}{}^{78}{}_{}{}^{}\mathrm{Zr}$, ${}_{}{}^{80}{}_{}{}^{}\mathrm{Zr}$, ${}_{}{}^{84}{}_{}{}^{}\mathrm{Mo}$, ${}_{}{}^{86}{}_{}{}^{}\mathrm{Mo}$, ${}_{}{}^{88}{}_{}{}^{}\mathrm{Ru}$, ${}_{}{}^{90}{}_{}{}^{}\mathrm{Ru}$, ${}_{}{}^{92}{}_{}{}^{}\mathrm{Pd}$, and ${}_{}{}^{96}{}_{}{}^{}\mathrm{Cd}$. The calculation is based upon the random phase approximation with the quasiparticle formalism and takes into account the residual particle-particle interaction.
