摘要: Empirical equations for the estimation of fission fragment yield are proposed. These can be applied to all nuclides in nuclidic region 208≲A andZ2/A 250 accumulate. nuclei withA>250 produced byr-process and make delayed spontaneous fissions duringr-process cooling. Furthermore, a possibility is proposed that anomalously high abundance medium weight elements observed some peculiar A stars may accumulation fragments from fissioning 250≲A≲265.
