The angular distributions for low lying states of 16O produced in the 12C(6Li, d)16O α-transfer reaction at have been measured using a high energy resolution position sensitive detection system. The measured cross section data have been analyzed by the FRDWBA theory with a particular emphasis put on the states of astrophysical interest mainly the (7.12 MeV) state. Extracted values of nuclear level parameters (excitation energy, , line width, , α-spectroscopic factor, , and reduced α-width, or ) are reported and discussed in comparison to previous ones. The used binding potential corresponds to a long nuclear interaction range (up to a channel radius ), suggesting that the channel radius is likely suitable for the calculations of reduced α-widths near the nuclear surface. However, given that previous DWBA results are available for comparison only near the channel radius , calculations have been carried out here for both three preceding a values. Formal values, and of the reduced α-widths () of the (7.12 MeV) and (6.92 MeV) states have thus been derived. Furthermore, the R-matrix analysis of various data sets of importance to the 12C()16O direct capture reaction has been carried out, leading to the range of values for the (7.12 MeV) state, , which is consistent with the preceding DWBA interval, and to a result for the E1 component of the reaction astrophysical factor, , very consistent with most constrained values previously reported in the literature.
