The results of experimental studies of the emergence of ultracold neutrons (UCN) from solid deuterium, which were performed on a model source in the BBR-M reactor at the St. Petersburg Institute of Nuclear Physics, are reported. The temperature gain factor in the UCN yield at 13-14 К from solid deuterium relative to to the UCN yield at room temperature from a gaseous state is equal to 1230 and 550 at solid-deuterium temperature of 18.7 К (triple point). © 1995 American Institute of Physics.
