    "abstract": "Pion and kaon mean free paths within a thermal hadronic background are\ncalculated using relativistic kinetic theory. Free cross sections are used\nwhich include contributions from $\\rho$, $K^{*}$, $\\Delta$ and heavier\nresonances. Given pion to baryon ratios appropriate for the breakup stage of a\n$200\\cdot A$GeV relativistic-heavy-ion collision, we find for temperatures less\nthan 100 MeV, kaons have a shorter mean free path than pions, while for higher\nbreakup temperatures the reverse is true. Since breakup temperatures should be\nin the neighborhood of 100 MeV, this suggests that kaon interferometry samples\nthe same emission distribution as pion interferometry.",
