文摘The cross section for the J^(π)(T)=3^(+)(0)state was measured to be enhanced in an isolated 6Li nucleus compared to the same reduced state in a ^(6)Li cluster.This difference demonstrates a nuclear medium modification of the tensor force,which is sensitively probed by the T=0 channel.In contrast,the J^(π)(T)=0^(+)(1)state(T=1)was found to have approximately equal excitation strength in both ^(6)Li systems.We interpret this tensor force modification as a consequence of density saturation within a many-body interaction framework.
