A discussion is given on possible realization of the Single State Dominance (SSD) hypothesis in the case of the two-neutrino double beta decay (2{nu}{beta}{beta}-decay) of {sup l50}Nd with 1{sup -} ground state of the intermediate nucleus. We conclude that the SSD hypothesis is expected to be ruled out by precision measurement of differential characteristics of this process in running NEMO 3 or planed SuperNEMO experiments unlike some unknown low-lying 1{sup +} state of {sup 150}Pm does exist. This problem can be solved via (d,{sup 2}He) charge-exchange experiment on {sup l50}Sm. Further, we address the question about possible violation of the Pauli exclusion principle for neutrinos and its consequences for the energy distributions of the 2{nu}{beta}{beta}-decay of {sup l50}Nd. This phenomenon might be a subject of interest of NEMO 3 and SuperNEMO experiments as well.
