چکیده انگلیسی
As shown in Rodin and Faessler (2009) [7], the Fermi nuclear matrix element MF0ν of neutrinoless double beta (0νββ) decay can be reconstructed if one is able to measure the isospin-forbidden single Fermi transition matrix element from the ground state of the final nucleus to the isobaric analog state (IAS) of the initial nucleus, for instance by means of charge-exchange reactions of the (n,p)-type. Here, simple estimates for 82Se are made which show that indeed the tiny cross-section Ïnp(0f+âIAS) is dominated by the admixture of the double IAS in the ground state of the final nucleus provided that the isospin mixing is weak and can be treated perturbatively. A measurement of such a cross-section would definitely be a very difficult task, but it can advance a lot our knowledge of the 0νββ nuclear matrix element.
