“…The spin parities of the states in 60 Zn have also been studied in the previous measurements, mostly focusing on low-lying states (Greenfield et al 1972;Pougheon et al 1972;Winsborrow & Macefield 1972;Evers et al 1974;Kamermans et al 1974;Alford et al 1975;Weber et al 1979;Schubank et al 1989;Boucenna et al 1990;de Angelis et al 1998;Svensson et al 1999;Mazzocchi et al 2001). For high energy states above the proton threshold, only a few studies have been conducted on each energy state, but there are frequent discrepancies in those measurements.…”

Type I X-ray bursts (XRBs) are powered by thermonuclear burning on proton-rich unstable nuclides. The construction of burst models with accurate knowledge of nuclear physics is required to properly interpret burst observations. Numerous studies that have investigated the sensitivities of burst models to nuclear inputs have commonly extracted the strength of the NiCu cycle in the rp process, determined by the 59Cu(p,α)56Ni and 59Cu(p,γ)60Zn thermonuclear reaction rates, as critical in the determination of reaction flow in the burst. In this study, the strength of the cycle at the XRB temperature range was estimated based on published experimental data. The nuclear properties of the compound nucleus 60Zn were evaluated for the 59Cu(p,α)56Ni and 59Cu(p,γ)60Zn reaction rate calculations. Monte Carlo rate calculations were conducted to include the large uncertainties of nuclear properties in the calculations. In the current work, a weak NiCu cycle is expected, whereas the rates adopted by the previous studies suggest a strong NiCu cycle. Model simulations were performed with the new rates to assess the impact on Type I XRBs. The results show that the estimated cycle strength does not strongly influence the model predictions of the burst light curve or synthesized abundances.
