Summary
The Λ-Λ potential strength is estimated from the binding energy of4HΛΛ as predicted by an extension of the unitary symmetry argument to bound states of baryons. All the potentials are assumed to have Gaussian shapes and a modification of a method due to Green is used for the calculations. The values obtained are larger than those obtained by Dalitz and others from the binding energy of10BeΛΛ.
Riassunto
Si valuta l’intensità del potenziale Λ-Λ in base all’energia di legame4HΛΛ quale è predetta da un’estensione dell’argomento della simmetria unitaria agli stati legati dei barioni. Si suppone che tutti i potenziali abbiano forme gaussiane e per i calcoli si usa una modifica del metodo di Green. I valori ottenuti sono maggiori di quelli ottenuti da Dalitz ed altri dall’energia di legame del10BeΛΛ.
