The dynamical decays of random, unstable, negative-energy, n-body systems have been followed numerically, to investigate the statistics of stable decay products. From initial quadruple systems, about 20% of the products were stable triples while 30% resulted from initial quintuple systems. These numbers are consistent with the observed ratio of triples to binaries, especially for the higher-multiplicity initial systems.

Resumen

Resumen

Se ha seguido numéricamente el decaimiento dinámico de sistemas de N cuerpos, casuales, inestables y de energia negativa para investigar la estadística de los productos estables del decaimiento. De sistemas iniciales cuádruples, el 20% de los productos fueron triples estables, mientras que el 30% resultó de sistemas inicialmente quintuples. Estos números son consistentes con la proporción de triples a binarias, especialmente para los sistemas de multiplicidad inicial alta.
