Here, applying the Scale-Symmetric Theory (SST), we described the origin and the spectra of the gamma-ray bursts (the exploding objects/progenitors we will call the GRBs). The GRBs explode due to the inflows of the dark energy into the associations of neutron black holes that are the constituents of the black holes in centres of galaxies. The GRBs should be placed near the Schwarzschild surface in the plane of the accretion discs. The bursts should be correlated with an increase in activity of the central-black-hole jet and accretion disc because it causes more dense flows of the dark energy. Such flows cause that the neutron black holes swell so their associations can transform into iron object. The increase in gravitational energy of the iron object is compensated by the decrease of the gravitational energy of the black holes as a whole, i.e. the central black holes become the more compact objects. A half of radiation energy is absorbed by the central black hole so the escaping energy looks as an analog to the Hawking radiation. The bursts are volumetric, not directional. Calculated here the typical emitted energy is equivalent to 1.9 solar masses. Most important are the fusions of nucleons mostly into iron-56 via helium-4, the beta decays of neutrons, and emission of photons with energy about 188 MeV that follows from the atom-like structure of baryons. According to SST, the radius of the observed Universe increased 46.55 times so the spectra of most distant GRBs (SST shows that galaxies with redshift higher than 0.6 all are in time distance about 13 – 13.8 Gyr) should peak near 17 keV, 150 keV, 190 keV, and 4 MeV. The spectra of GBRs placed, for example, in distance 1.2 Gyr should peak near 190 keV, 1.7 MeV, 2.2 MeV, and 46 MeV. But there can be other lower peaks as well. Most important are two results i.e. the released typical energy 1.9 solar masses and the peak for 150 keV or 190 keV for very distant GRBs because number density of photons emitted during the iron production from nucleons via helium-4 should be highest and because abundance of the gamma-ray bursts should be highest for the distant Universe.
