Experimental Indications for the Response of the Spectators to the Participant Blast

Nuclear Experiment 2009-11-10 v1

Abstract

Precise momentum distributions of identified projectile fragments, formed in the reactions 238U + Pb and 238U + Ti at 1 A GeV, are measured with a high-resolution magnetic spectrometer. With increasing mass loss, the velocities first decrease as expected from previously established systematics, then level off, and finally increase again. Light fragments are on the average even faster than the projectiles. This finding is interpreted as the response of the spectators to the participant blast. The re-acceleration of projectile spectators is sensitive to the nuclear mean field and provides a new tool for investigating the equation of state of nuclear matter.
