Atomic Mass Extrapolations
These days ever more data come available on reaction energies connecting pairs of nuclides which are not themselves connected to the system of primaries (nuclides which are connected to each other in many ways). It is the aim of the Atomic Mass Adjustment program1) to compare all available data, to check the system for internal consistency and to produce a list of atomic masses and linear combinations of atomic masses. Therefore unconnected data should be made connected in some way to become usefull inputdata for the program. Up till now this was done by adding so called systematics to the inputdata: binding energies of two protons or two neutrons, alpha- and (double) beta-decay energies were used since they will be influenced only slightly by paring energies. Values were calculated by manual extrapolation in the graphs for the four quantities simulteneously. Today some thousand systematic data are necessary to connect all the available data so this procedure has become a very time consuming part of the preparation. In this paper an attempt is presented to computerize this part of the work.
