AbstractAbstract
[en] Comparison of experiments on the study of the Bose-condensate density in helium 2 by the neutron scattering method is presented. The case is considered when the initial energy of incident neutrons falling on the He2 sample is much higher than the mean energy of 4He thermal atom motion (Esub(i) > > T) as Well as the Esub(i) approximately T case. The evaluation of the 4He atom free motion relaxation in He2 in the Esub(i) approximately T case is carried out from which it follows that the Bose-condensate density constitutes n0(1.2 K)=8.8+-1.3 1020 cm-3 and n0(1.9 K)=6.3+-1.3 1020 cm-3
