The Maxwellian-averaged cross-sections (MACS) and neutron-capture rates for the stable isotopes 136 Ce, 138 Ce, 140 Ce, and 142 Ce have been computed within the framework of the statistical model using the TALYS v2.0 code. The study investigates the impact of phenomenological, microscopic nuclear level densities (NLDs) and photon strength functions (PSFs) on the MACS and neutron-capture rates. The computed MACS values obtained from the model are in good agreement with the available literature. The neutron-capture rates, λ (n , γ) (in s -1 ), were derived using the constrained MACS values. Constraining the theoretical predictions with the available experimental data enables a more reliable exploration of the s-process network. Furthermore, the β+/EC rates, λ (β++EC) (in s -1 ), for the 136 Ce, 138 Ce, 140 Ce, and 142 Ce were analyzed within the pn-QRPA framework under conditions relevant to the s-process. The present analysis shows that λ (n, γ) remains higher than λ (β++EC) under the adopted s-process conditions.
