  We discuss the possibility for a cooled down and otherwise stable solitary
neutron star to make a spontaneous transition to its potential black hole
ground state. This fundamental process would mimic a precursorless explosion in
which the emitted radiations consisting of the statistical mass spectrum of
high-energy neutron-rich nuclei, gamma rays and (anti) neutrinos, would carry
away some mass of the star, leaving behind the core of the star in the form of
a black hole.
