  11. A Bolometric calibration by pulsed heating s1/√T

  12. In 3He + n reaction 9% +- 1% of energy going for scintillation H. Godfrin G. R. Pickett G.M.Seidel

  13. From the fit, the energy emitted into a solid angle of 4p steradians is 87 keV, or 24% of the total energy of the 364 keV electron. In contrast, for an alpha particle stopped in helium we found, upon correcting for reflectivity, that only 10% of the initial energy of the particle is emitted as uv radiation.

  18. Ultra Low Temperature Instrumentation for Measurements in Astrophysics The idea : Use the Bose –Einstein condensed coherent quantum state of superfluid 3He at a limit of extremely low temperatures as a sensitive medium for the direct bolometric search of non-baryonic Dark Matter First suggestion G.R.Pickett in Proc. «Second european worshop on neutrinos and dark matters detectors», ed by L.Gonzales-Mestres and D.Perret-Gallix, Frontiers, 1988, p. 377. Yu.Bunkov, S.Fisher, H.Godfrin, A.Guenault, G.Pickett. in Proc. « International Workshop Superconductivity and Particles Detection (Toledo, 1994)», ed. by T.Girard, A.Morales and G.Waysand. World Scientific,p. 21-26.

  19. Bose – Einstein condensed coherent quantum state with rear gas of collective excitations. At about 100 mK at 0.1 cm3 remains only 10 keV from the level of absolute zero of temperature. Temperature is the density of quasiparticles, that measured directly by damping of mikro vibrating wire. The deposited energy is intimately associated with the 3He nuclear. There is no isolated nuclear thermal bath, separated from electronic and phononic subsystems!
