We further find that anti - flow appears at certain large impact parameter , which seems to be more sensitive to 2 and might provide more definite information of the magnitude of 2 . the absorption effect of k - mesons is also studied , we find although there exists strong k - absorption , k - spectrum can still contain the messages of at " in nuclear medium 接著我們又研究了k ~ -介子的吸收問題,發(fā)現(xiàn)雖然有強烈的k ~ -吸收存在,其能譜在不太重的核系統(tǒng)的非中心碰撞中仍顯示出對為的依賴,有可能提供k在核介質(zhì)中性質(zhì)的知識。
