    "abstract": "Differential cross sections for $^3$He-$\\alpha$ scattering were measured in\nthe energy range up to 3 MeV. These data together with other available\nexperimental results for $^3$He $+ \\alpha$ and $^3$H $+ \\alpha$ scattering were\nanalyzed in the framework of the optical model using double-folded potentials.\nThe optical potentials obtained were used to calculate the astrophysical\nS-factors of the capture reactions $^3$He$(\\alpha,\\gamma)^7$Be and\n$^3$H$(\\alpha,\\gamma)^7$Li, and the branching ratios for the transitions into\nthe two final $^7$Be and $^7$Li bound states, respectively. For\n$^3$He$(\\alpha,\\gamma)^7$Be excellent agreement between calculated and\nexperimental data is obtained. For $^3$H$(\\alpha,\\gamma)^7$Li a $S(0)$ value\nhas been found which is a factor of about 1.5 larger than the adopted value.\nFor both capture reactions a similar branching ratio of $R =\n\\sigma(\\gamma_1)/\\sigma(\\gamma_0) \\approx 0.43$ has been obtained.",
