Studies in Fuzziness and Soft ComputingThe fact that particles do not lose their energy in a target continuously, but in discrete steps, can result in a considerable change of the apparent shape and position of a resonance. A method for determining the shift of the midpoint in a yield curve for thick targets is sketched and numerical results are given in graphical form.

Representations: From Words to ImagesA set of accurate Q-values has proven to be of some use in many respects. The question whether further reduction of the errors into the sub-keV range warrants some extra efforts can better be discussed after a stock-taking of the technical possibilities and a discussion of some applications.

https://doi.org/10.1007/978-3-319-47190-7Recently, the accuracy of doublet mass measurement has been greatly increased and the atomic masses are determined with an accuracy as small as one part in 10.(1). In such a high accuracy measurement, the relative image position of the components of mass doublet should be measured with an accuracy of the same order.

On-line Mass Spectrometric Analysis of Far Unstable Light Nuclei Produced in High Energy Nuclear ReaIn the last five years or so, a large number of very neutron rich isotopes of the light elements have been identified. Fig. 1 shows the changes brought in this part of the chart of the nuclides through the work done by groups at Berkeley, Princeton, Orsay and Doubna (1).

Fuzzy Relation Equations with Words, only a moderately accurate energy scale is actually needed. Further, an absolute spectrometer has necessarily such a low transmission that it is of little use in more advanced ∝- ray work. Nevertheless, there are several good reasons why reliable ∝-energy standards are of considerable importance.
