REGULARITIES OF THE DYNAMICS OF SPHERICAL EXPLOSIONS IN HOMOGENEOUS GASES A. M. Petrenko , G. S. Romanov , A. N. Chumakov , and V. V. Efremov UDC 534.222.2:621.373 It is found that the calculated recoil momentum for sufficiently large target radii is negative irrespective of the variations in the equation of state, whereas the experimentally measured value is positive regardless of the target dimensions. An explanation for the difference revealed is proposed.JEPTER74920199817 JEPTER7492017
