  A novel method for a direct measurement of the exclusive Lambda_c^+ branching
ratios is here described. The approach is based on the peculiar topology of the
quasi-elastic charm neutrino-induced events on nucleons. The intrinsic
potentiality of the method is thoroughly discussed using a "perfect detector".
As an application, the statistical accuracy reachable with existing data sample
has been estimated. From a theoretical point of view, such measurement provides
a better understanding of the baryonic b-decays.
