The half lives of the noble gas precursors of the nuclides used above ére: csl¥7, 3.8 min.; Sr®89, 3.2 min.; Sr%, 33 sec.; Y9, 10 sec.; Cols w1 sec.; Cst96none. The fraction of Mo?? remaining in the cloud as calculated by each of these nuclides increases inversely as the half life of the nuclides noble g2s precursor. This indicat that these nuclides and their precursors were not distributed in the same ratio throug) out the cloud even at very early times. If they were so distributed, the fraction of 85(a)
