Description
The Nuclear level density and (\gamma)-ray Strength Function are primary ingredients for astrophysical reaction rate calculations based on the Hauser-Feshbach approach. These parameters need to be well understood to improve our understanding of (^{182})Hf production in astrophysical environments. The new experimentally constrained (\gamma)SF and NLD in (^{181,182})Hf were extracted, using the Oslo method first-order phase transition. In particular, a (^{181})Ta(d,X), at 15 MeV experiment was conducted at Oslo cyclotron in which the NaI(Tl) and silicon detectors were used to detect (\gamma)-rays and (\alpha) particles. The particle coincidence events were used to extract NLDs and (\gamma)SF of (^{179,180})Hf from which those of (^{181,182})Hf were inferred. Based on these experimental results the Maxwellian averaged (n, (\gamma)) cross-sections of (^{180})Hf(n,(\gamma)) and (^{181})Hf(n,(\gamma)) reactions were computed with the TALYS reaction code. These results can be used to shed some light on the nucleosynthesis puzzle of (^{182})Hf.
