Summary
The neutron to proton stimulation ratio of the Λ-hyperon (Λn/Λp) in the nonmesonic decays of heavy hyperfragments of massA≳10 produced from the K− captures in nuclear emulsion is studied. The procedure is based on the comparison of the experimental proton and total visible energy spectra at the decay centres of hyperfragments with the corresponding results obtained from the Monte Carlo calculations. The value of the ratio is estimated to be ≈2.
Riassunto
Si studia il rapporto di stimolazione fra neutrone e protone per l'iperone Λ (Λn/Λp) nei decadimenti non mesonici di iperframmenti pesanti di massaA≳10 prodotti da catture di K− in emulsione nucleare. Il procedimento si basa sul confronto fra lo spettro d'energia sperimentale del protone e lo spettro dell'energia visibile totale ai centri di decadimento degli iperframmenti con i corrispondenti risultati ottenuti dai calcoli col metodo di Monte Carlo. Si valuta che il valore del rapporto è ≈2.
Резюме
Исследуется (Λn/Λp) отношение для Λ гиперона в немезонных распадах тяжелых гиперфрагментов с массойA≳10, рожденных при захвате K− в ядериых змульсиях. Рассматриваемая процедура основана на сравнении зкспевиментальных протонного и полного наблюдаемых знергетических спектров с соответствующими результатами, получаемыми из вычислений по методу Монте-Карло. Оценка величины зтого отношения составляет ≈2.
