Indirect Measurement of ⁹⁵Zr(n, γ)⁹⁶Zr

⁹⁵Zr(n, γ)⁹⁶Zr cross section is important for the study of stellar evolution and heavy elements nucleosynthesis because the reaction is the only way to produce the ⁹⁶Zr in Asymptotic giant branch stars. The direct measurement of ⁹⁵Zr(n, γ)⁹⁶Zr is very difficult due to the short half-life of ⁹⁵Zr, 64 days. The surrogate ratio method was carried out to measure ⁹⁵Zr(n, γ)⁹⁶Zr cross sections. We measured the ⁹⁴Zr(¹⁸O, ¹⁶Oγ)⁹⁶Zr and ⁹⁰Zr(¹⁸O, ¹⁶Oγ)⁹²Zr reactions and obtained the γ-decay probability ratio of compound nuclei ⁹⁶Zr^* and ⁹²Zr^*. The ⁹⁵Zr(n, γ)⁹⁶Zr cross section is determined by the obtained ratio multiplying the known ⁹¹Zr(n, γ)⁹²Zr cross section at E_n=0~8 MeV.
