Experiments were carried out in order to find a means for retaining slow neutrons. It is suggested that the neutrons be subjected to preliminary cooling in liquid helium. Due to the long lifetime of the slow neutron, within a few seconds the concentration becomes equal to Maxwellian equilibrium. The main difficulties are related to the necessity of retaining a large volume of helium to accommodate the long paths in helium (50 cm). With a reactor flux of 10/sup 12/, the retarded flux at 3 deg K would be 10/sup 11/, corresponding to a thermal neutron density of 5 x 10/sup 6/cm/sup -3/ and a cold flux ot 50/cm/sup -3/. Consequently, under favorable conditions it is possible to store 5 x 10/sup 7/ cold neutrons. (R.V.J.)
