摘要
Three-dimensional source images for mid-rapidity, low transverse momentum kaon and pion pairs have been extracted from central Au + Au collisions data at √sNN = 200 GeV by the STAR experiment at RHIC. The pion source function displays significant non-Gaussian features implying a finite pion emission duration. On the other hand, the kaon source function is essentially Gaussian, consistent with instantaneous emission from the fireball. © 2011 Pleiades Publishing, Ltd.
