The neutron rich neck zone created in heavy ion reaction is experimentallyprobed by the production of the $A=3$ isobars. The energy spectra and angulardistributions of triton and $^3$He are measured with the CSHINE detector in$^{86}$Kr +$^{208}$Pb reactions at 25 MeV/u. While the energy spectrum of$^{3}$He is harder than that of triton, known as "$^{3}$He-puzzle", the yieldratio $R({\rm t/^3He})$ presents a robust rising trend with the polar angle inlaboratory. Using the fission fragments to reconstruct the fission plane, theenhancement of out-plane $R({\rm t/^3He})$ is confirmed in comparison to thein-plane ratios. Transport model simulations reproduce qualitatively theexperimental trends, but the quantitative agreement is not achieved. Theresults demonstrate that a neutron rich neck zone is formed in the reactions.Further studies are called for to understand the clustering and the isospindynamics related to neck formation.
