The EXFOR format, which is widely used for compiling neutron cross section data, was adapted for the present purpose [CINDA97]. This format provides for an easily deciphered, platform-independent ASCII representation of both textual and numerical data. Furthermore, it is a format which is generally familiar to investigators in the nuclear data community. Since the EXFOR format has been used in the past almost exclusively for compiling data on neutron reactions, some creativity had to be exercised in producing the present files of data relevant to charged-particle reactions and properties of reaction-product nuclei while still preserving most of the historical characteristics of the file structure. These files have been sent to the National Nuclear Data Center, Brookhaven National Laboratory, Upton, New York, U.S.A., for inclusion in the library of data on charged-particle reactions which is being collected there.
