Relativistic Mean Field (RMF) theory with density-dependent forces (DD-ME2 and DD-PC1) was utilized to investigate decay modes and half-life of superheavy No247-266 isotopes. Triaxially deformed RMF model was used to obtain potential energy surfaces (PESs) of the considered nuclei which is used to determine their ground-state (g.s.) shape. By regarding PES results, axially deformed RMF calculations have been employed to obtain g.s. binding energy (BE) of No247-266 nuclei. The calculated g.s. BE values of the nobelium isotopes have been used for the prediction of alpha, beta(+)/EC, beta(-) and spontaneous fission (SF) decay modes and half-life of No247-266 isotopes. Our results show that the No247-266 isotopes are well deformed and their shapes are predicted to be prolate. According to existing experimental data, our estimates for decay modes and half-lives are in agreement.
