Regularities of the dynamics of spherical explosions in homogeneous gases

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.[...
