The longitudinal momentum distributions of core fragment from one nucleon removal reaction were calculated taking into account the core absorption effect within the Glauber multiple scattering model[1]. The (^<11>Be, ^<10>Be)[2], (^8B, ^7Be)[3], and (^<19>C, ^<18>C)[4] reaction on the light target are taken as typical examples of the 5, p, and d orbitals of last nucleon. The core absorption effect depends on the angular orbital of the last nucleon. Taking into account this effect we obtained the following results on the each reaction. The first, there is almostly no effect on the 11Be case. The second, we can consistently understand the narrow width of ^7Be fragment with spatial extent like the normal p-shell nuclei of ^8B. The third, our calculated result shows that the s-state is dominant component in the ground state of ^<19>C.
