Abstract
The possibility is discussed that the enhanced clustering in the nuclear surface of some nuclei observed by Samanta et al. [Phys. Rev. C 26, 1379 (1982)] is due to the modification of the wave function of a discrete nuclear state at the nuclear surface by unbound states. The modification is formulated in a model with unified description of bound and unbound states. Experimental data from knockout reactions on odd nuclei are necessary in order to test the theoretical statements.
