The FINUDA experiment at DAΦNE, Frascati, has found evidence for the neutron-rich hypernucleus studying (π+, π−) pairs in coincidence from the production reaction followed by weak decay. The production rate of undergoing this two-body π− decay has been found to be . Its binding energy has been evaluated to be MeV with respect to , jointly from production and decay. A systematic difference of (0.98 ± 0.74) MeV between BΛ values derived separately from decay and from production has been tentatively assigned to the excitation. A similar investigation has been carried out for the neutron-rich hypernucleus studying the reaction in coincidence with the weak decay; an upper limit for the production rate of undergoing the two-body π− decay has been found to be (90% C.L.).
