Zusammenfassung

The ground-state spins and magnetic moments of ^49,51K have been measured using bunched-beam high-resolution collinear laser spectroscopy at ISOLDE CERN. For ⁴⁹K a ground-state spin I=1/2 was firmly established. The observed hyperfine structure of ⁵¹K requires a spin I>1/2 and strongly suggests I=3/2. From its magnetic moment μ(⁵¹K)=+0.5129(22)μ_N a spin-parity I^π=3/2⁺ with a dominant π1d_3/2^-1 hole configuration was deduced. This establishes for the first time the reinversion of the single-particle levels and illustrates the prominent role of the residual monopole interaction for single-particle levels and shell evolution.
