Beta‐decay half‐lives for the free neutron, for 6 He and 8 He, and for 8 Li are calculated ab initio from geometrical thermodynamics arguments, independently of any quantum mechanics. Half‐lives for the decay of 8 Be to two alphas and for the disintegration of the tetraneutron are also calculated. The calculated values are close to those experimentally observed.
