## Abstract The characteristic time of exciton relaxation due to phonons is estimated, and as it turns to be smaller than the exciton lifetime, it is concluded that Bose‐Einstein condensation is possible in the system of Frenkel excitons. It is further shown that kinematical interaction obtained in
Using a capacitive pressure gauge, the pressure of a constant-volume 4Hesample was measured in the temperature range 1.5-120 mK, at pressures of 25.3 bar (on the melting curve) and26.0 bar. A gradual pressure change occurring as a consequence of the ideal gas behavior of vacancies, or a pressure ano
