Bilenky, Samoil M.Petcov, Serguey T.2007-11-142011-09-072007-11-142011-09-072007-11-14https://openscience.sissa.it/handle/1963/2415A possible model independent test of the theoretically calculated nuclear matrix elements of $0\nu\beta\beta$-decay is proposed. The test can be accomplished if $0\nu\beta\beta$-decay of three (or more) nuclei is observed. The selection of the nuclei for the next generation of $0\nu\beta\beta$-decay experiments should be done taking into account {\it also} considerations regarding the possibility to test the nuclear matrix element calculations.167818 bytesapplication/pdfen-USPreprint
