[en] In explosive hydrogen burning nucleosynthesis material is processed via the proton capture sequence ³⁹Ca(p,γ)⁴⁰Sc(p,γ)⁴¹Ti. It has been predicted that the isotope ³⁹Ca represents a waiting point for a continuous reaction flow. Therefore, its reaction rate is of interest. The ³⁹Ca(p,γ)⁴⁰Sc reaction rate is determined by three resonances corresponding to the 2nd, 3rd and 4th excited states of ⁴⁰Sc. Improved nuclear structure information of the low-lying levels of ⁴⁰Sc is necessary to reduce uncertainties in the reaction rate of ³⁹Ca(p,γ)⁴⁰Sc. Results from a current measurement of ⁴⁰Ca(³He,t)⁴⁰Sc at TUNL indicate that the 4th excited state is a doublet and further investigation is warranted
