Preliminary results on the 2p levels of krypton obtained by the Hanle effect

Using Hanle experiments in a discharge, the radiative lifetimes of 7 out of the ten 2p-levels of krypton have been studied as well as the cross-sections for the destruction of alignment in these levels by collisions with ground-state krypton atoms. The limitations of the present experimental method are emphasized and plans for future improvements are formulated.
