When this first came up we found another Charles Hawkins, a lecturer with the Physics department at University of Texas, El Paso. The name was apparently the only connection. From a brief view of the page he appears to be inactive from the university but is certainly of the right age to have published papers at that time. The paper is far more likely to be from the scientist rather than the sham author.
