Based on Glauber Multiple Scattering Theory, high-energy proton elastic scattering on halo-like nucleus C-13 is studied in a single nucleon wave function with low angular momentum configurations. A g eat agreement with or experimental data is obtained and the theoretical prediction clearly shows that C-13 has a neutron halo-like structure. Then, the origin and nature of nuclear halo phenomena are explained in terms of nuclear short-range correlations. Our conclusion shows that the origin of nuclear halo-like phenomena originates from short range nuclear correlation.
