Farli calculations by the authors (zhETr v. 44, 660,
1963) in the f!ree-collision approximation did not yield a sufficiently complete and
correct picture of the effect of variation of the colliding-particle velocity or of'
charge on the cross sections. The nonrelativistic Born approxtmatiQn is used in th
the present article, and the energy and velocity ranges in which this approxftation
ia valid are determined. The relative contribix~;ions of elastic and inelastic in-
teractions are campareda For low-charge ions the approximation yields cross see-

TEXT: The Zeeman effect of the members of the yellow exciton series of
directed.Cu 2 0 crystals was examined in magnetic fields of.up to 140 koe

cooled in. liquid helium. With increasing field strength the line splitting
grows more complex with rising.main quantUm number n (Pauchen-Bak effect)$
The experiments with single.crystals showed clear.dependence beti;een the
splitting.and~the orientation of the crystal in the magnetic fi.eld.. The
