Abstract The hyperfine structure of the excited 3d 9 4s 4p 4 P 3/2-term of the Cu I-spectrum was investigated in a level-crossing experiment using an atomic beam with copper in natural abundance as absorber. From the level-crossing signals the following relations for the hyperfine structure constants were deducedA(Cu63)=2184.66 (17)g J /1.75 Mc/sec,B(Cu63)=−38.65 (11) gJ/1.75 Mc/sec,A(Cu65)=2340.15 (19)g J /1.75 Mc/sec,B(Cu65)=−35.69 (17) gJ/1.75 Mc/sec. The ratio of the magnetic hyperfine structure constants of Cu63 and Cu65 was determined with high accuracy to beA(Cu63)/A(Cu65)=0.93355 (2). From this ratio a hyperfine structure anomaly63Δ65(4 P 3/2)=1.4·10−4(4) was deduced. The width of the zero field crossing yielded a lifetime τ=3.2 (3) · 10−7 sec for the excited4P3/2-term.
