The three-, four-, and five-nucleon transfers were investigated by studying the ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$(α,${\mathrm{}}^7$Li${)}^7$Be, ${}_{}{}^{11}{}_{}{}^{}\mathrm{B}$${(}^3$He${,}^7$Li${)}^7$Be, and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(d${,}^7$Li${)}^7$Be reactions, respectively. The measurements were performed in the entire center of mass angular region, at incident energies corresponding to 49.3 MeV in the center of mass system of the exit channel. A distorted-wave Born approximation analysis was performed including second-order transfer contributions for all investigated reactions.
