[en] The ²⁸Si(p,t)²⁶Si reaction has been studied to resolve a controversy surrounding the properties of the ²⁶Si level at 5.914 MeV and its contribution to the ²⁵Al(p,γ)²⁶Si reaction rate in novae, which affects interpretations of galactic ²⁶Al observations. Recent studies have come to contradictory conclusions regarding the spin of this level (0⁺ or 3⁺), with a 3⁺ assignment implying a large contribution by this level to the ²⁵Al(p,γ)²⁶Si reaction rate. We have extended our previous study [Bardayan et al., Phys. Rev. C 65, 032801(R) (2002)] to smaller angles and find the angular distribution of tritons populating the 5.914-MeV level in the ²⁸Si(p,t)²⁶Si reaction to be consistent with either a 2⁺ or 3⁺ assignment. We have calculated reaction rates under these assumptions and used them in a nova nucleosynthesis model to examine the effects of the remaining uncertainties in the ²⁵Al(p,γ)²⁶Si rate on ²⁶Al production in novae
