. The temperature of degenerating is the temperature below which there appear the quantum effects connected with the indenty of the particles. For bose-gas this temperature Td is equal to the one below which the condensation of Bose-Einstein occurs. Td = Ef/ k , where Ef - maximum energy of particles at T = 0 (fermy-energy), k - constant of Boltzman ( k = 1,3807*10^-23 Dg/K). Back .
