Abstract

Experiments on the isotope shift of U²³³, U²³⁶, U²³⁵, U²³⁴, and U²³³ in the uranium emission line U I 5027.4 A are made with the photoelectric interferometer Hypeac. The ratios U²³⁵+U²³⁴/U²³⁸ and U²³³+U²³¹/U²³⁸ can be determined with the Automatic Electronic Integrator. The possibility of interference between the lines U²³⁵ 5027 295 A and U²³⁶ 5027.338 A is discussed
