Gamma-ray spectroscopy is the most prominent method of learning about the structure of the atomic nucleus and thus it is the most consistent part of the professional nuclear data evaluations, as the well-known ENSDF evaluations published by the US National Nuclear Data Center in Nuclear Data Sheets. On one side, precision is critical for a quantitative improvement of the nuclear data for science and technology, which we address by accurate measurements of conversion coefficients at TexasA&M Universitythat affects virtually all nuclear level schemes. At the other side we qualitatively question the significance of gamma-ray spectroscopy for drawing level schemes, based on new type of correlations we get out from data: what in fact is a level scheme, what in fact the nature of data is, and how they converge toward a new concept of level scheme and data.
