We introduce a method for isospin restoration in the calculation of nuclear matrix elements (NMEs) for 0 ν β β and 2 ν β β decay within the framework of the microscopic interacting boson model (IBM-2). With this method, we calculate the NMEs for all processes of interest in 0 ν β − β − and 2 ν β − β − and in 0 ν β + β + , 0 ν EC β + , R 0 ν ECEC , 2 ν β + β + , 2 ν EC β + , and 2 ν ECEC . With this method, the Fermi matrix elements for 2 ν β β vanish, and those for 0 ν β β are considerably reduced.
