Abstract—It is proposed that cosmic gamma-ray bursts (GRBs) are generated on old (t > 10⁸ yr), nearby (within <100 pc) neutron stars when their solid crusts crack as they readjust to the new equilibrium configurations as the neutron star rotation slows down. Such slowly rotating, old neutron stars could be either faint longperiod (p > 3 s) pulsars or weakly modulated variable radio sources. To match the observed rate of GRBs ( 1day^–1) to the mean density of old neutron stars in the Galactic disk (~10 ^{- 3} pc^–3), it is sufficient to assume that the interval between bursts on a single neutron star is a few decades.
