Results are presented from experimental studies of the neutron emission generated in the collision of deuterium plasma flows produced in discharges in crossed E x H fields and propagating in opposite directions in a neutral gas across an external magnetic field. It is shown that the interaction of oppositely propagating deuterium plasma flows gives rise to the generation of soft X-ray emission and neutron emission from the dd reaction (dd {yields} {sup 3}He + n) and is accompanied by an almost complete depolarization of the flows and rapid variations in the magnetic field (at a rate of {approx}10{sup 11} G/s). The measurements were performed at energies and velocities of the flows of up to 600 J and 3.5 x 10{sup 7} cm/s, respectively. The plasma density in each flow was {approx}10{sup 15} cm{sup -3}. The upper estimates for the astrophysical S factor and the effective cross sections of the dd reaction obtained from our measurements are compared to theoretical calculations and to the results of experiments performed in the MIG high-current accelerator (Institute of High-Current Electronics, Russian Academy of Sciences, Tomsk)
