We present total charge exchange cross sections for collisions of Li(1s22s2S) with H(1s) in presence of a linear polarized laser field of intensity 0.05 ≤ I ≤ 1 TW/cm2 and wavelength 5 103 ≤ λ ≤ 14 103 Å. Our calculation shows that the laser field can increase the cross section of this reaction by a factor of ten at impact energies E < 0.1 ke V/a.m.u. The mechanism of this process is discussed and it is shown that both atomic and molecular radiative transitions can take place depending on the laser wavelength employed.

The Cross

Charge exchange cross sections for the four systems He+, Ne+ + Ar, Kr have been measured, ap­plying slow ions gathering techniques. The values are several 1O-16 cm2 and are almost constant between 20 and 200 eV collision energy. The comparison with previously published data for charge exchange into optically excited higher states of the ions show that these reactions prefer at least at 25 to 30% endothermic channels instead of the exothermic one without excitation. - Additionally the cross section of the endothermic process Ar++Ne was measured. Above a threshold energy of 17 eV it shows a strong increase and a constant value of 7 · 10-17 cm2 between 20 and 200 eV.

Exchange Scattering

We present a model of backward π+p, π−p, and π−p charge exchange scattering consistent with our earlier approach to forward π−p charge exchange and backward π+p. We consider two body differential cross section data which exhibits a dip–bump structure as well as nonzero polarization. This is explained in terms of a dominant Regge pole vanishing at the dip accompanied by a background. The background is primarily responsible for the large u behavior of the cross section which includes the rise after the dip. It is assumed that the presence of nonzero polarization dictates this behavior. We isolate the I = 3/2 amplitude in π−p backwards and determine the I = 1/2 amplitude from π+p backwards. A prediction for π−p → nπ0 follows.

Abstract Investigations of the cross section for the reaction O- + O2 → O2- + O have been made for laboratory kinetic energies 0-100 eV. The reaction shows a sharp maximum in the cross section at low energies (5 eV lab.). By the use of the primary ion 18O- it can be shown that above 20 eV (lab.) there is only charge exchange whereas in the lower energy region ion-molecule-reactions as well as charge exchange occure. The reaction O- + O2 → O+ + … has also been observed above 27 eV (lab.).
