Two examples of rare modes of decay of hyperfragments

Two events, which appear to be rare decay modes of hyper-fragments, have been observed in a stack of nuclear emulsions exposed to the 23 GeV/c proton beam of the proton synchrotron at CERN. The first event is interpreted as due to the muonic decay of a lithium hyper-fragment and the second as due to the π+-mesonic decay of a helium hyper-fragment.


In un pacco di emulsioni nucleari esposto al fascio diprotoni di 23 GeV/o del protosincrotrone del CERN, si sono osservati due eventi che sembrano rari modi di deoadimento di iperframmenti. Si interpreta il primo evento come dovuto al decadimento muonico di un iperframmento di litio ed il secondo come dovuto al deoadimento mesonico π+ di. un iperframmento di elio.
