L103-7 ISSN: 0305-4616 CODEN: JPHGBM PLACE OF PUBL: UK TRANSLATED IN: A03 LANGUAGE: English YEAR: June 1987 COPYRIGHT NO: 0305-4616/87/060103+05$02.50 TREATMENT: T Theoretical or Mathematical ABSTRACT: FCC model predictions of nuclear RMS charge radial values are compared with empirical data for 341 isotopes across the periodic table. Using only one adjustable parameter the mean error is 1.55%, as compared with 1.42% in the extended liquid-drop model where three such parameters are required. The FCC model also implies a diffuse nuclear surface, a feature that demands ad hoc adjustments in other models, but is inherent in the FCC build-up procedure (15 Refs.)
