Abstract
Nuclei-candidates fit for γ-lasers of the SPTEN class which were selected firstly at 2001 are screened again. SPTEN (Soft Prompt Transplantation of Excited Nuclei, Karyagin, 1983, 1995) is the unique class in which the knot of contradictions between pumping, lasing, and active medium's cooling could be extricated. The amplification growth's and seed photon wait's stages are two phases of the stage before generation (SBG) which comes before the mirrorless lasing. Main features of SBG booked in present screening are: (1) The time-life of spontaneous photon could be raised via the prolongator (Karyagin, 1997, 2001). (2) The evolution of SBG and generation stages are governed via the amount of the prolonged amplified modes which could be controlled via the prolongator's length and size of blind. The last two things in SBG weigh on the qualification rank of nuclei-candidates through a force on the γ-lasing's quality. Particularly that rank depends on confinement in which γ-laser is working: in close space of land laboratory or in cosmic space. Such detailed examination of the mirrorless γ-mode selection principles (Karyagin, 1997 - 2003) is issued firstly.
