What the article says around this equation
where is the mean waiting time between successive neutron captures on a given nucleus and is that nucleus’s beta-decay half-life. Because the s-process obeys this inequality, its reaction path never strays far from the valley of nuclear stability: a nucleus captures a neutron, and if the product is unstable it decays back toward stability long before it can capture another neutron and be pushed further away [ 7 ] .
