The nonmesonic decays of heavy hyperfragments

Немезонные распады тяжелых гиперфрагментов

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The nonmesonic decays of heavy hyperfragments of massA=20, 40, 60, 80 and 100 are studied through Monte Carlo simulation. The complete decay process including the initial ΛN interaction, the nuclear cascade and the nuclear evaporation is simulated. Information is obtained on the characteristics of the decay star. An attempt is made to infer the mass region of the decaying hyperfragments from the prong distribution of the decay star. It is inferred that the neutron-to-proton stimulation ratio for the heavy hyperfragments may have any value ranging from 1 to 9.

Riassunto

Per mezzo di una simulazione di Montecarlo si studiano i decadimenti non mesonici degli iperframmenti di massaA=20, 40, 60, 80 e 100. Si simula l’intero processo di decadimento compresa l’interazione iniziale ΛN, la cascata nucleare e l’evaporazione nucleare. Si ottengono informazioni sulle caratteristiche della stella di decadimento. Si tenta di inferire la regione di massa degli iperframmenti che decadono sulla base della distribuzione dei rami della stella di decadimento. Si deduce che il rapporto di stimolazione fra neutroni e protoni per gli iperframmenti pesanti può avere ogni valore compreso fra 1 e 9.

Резюме

С помощью моделирования Монте-Карло исследуются немезонные распады тяжелых гиперфрагментов с массойA=20, 40, 60, 80 и 100. Моделируется полный процесс распада, включая начальное ΛN взаимодействие, ядерный каскад и ядерное испарение. Получается информация о характеристиках звезды распада. Предпринимается попытка сделать заключение о массовой области распадающихся гиперфрагментов из распределения лучей в звезде распада. Утверждается, что отношение нейтронного и протонного возбуждения для тяжелых гиперфрагментов может иметь любое значение в интервале от 1 до 9.
