Abstract
New data imply that the average velocity of radio pulsars is large. Un der the assumption that these data imply that a pulsar is born with an ''intrinsic'' kick, we investigate whether such kicks can be a conseq uence of asymmetrical stellar collapse and explosion. We calculate the gravitational wave signature of such asymmetries due to anisotropic n eutrino radiation and mass motions. We predict that any recoils impart ed to the neutron star at birth will result in a gravitational wave st rain h(zz)(TT) that does not go to zero with time. Hence, there may be ''memory'' in the gravitational wave form from a protoneutron star th at is correlated with its recoil and neutrino emissions.
