ABSOLUTE CHARGE-EXCHANGE CROSS-SECTIONS FOR THE INTERACTION BETWEEN SLOW -LESS-THAN-OR-EQUAL-TO-Q-LESS-THAN-OR-EQUAL-TO-43) PROJECTILES ANDNEUTRAL HE, AR, AND XE( (15)

We report measurements of absolute cross sections for single- and mult iple-electron capture in slow collisions (upsilon similar to-0.1-0.2 a .u.). Partial cross sections for simultaneous r-electron removal from the target and p-electron retainment by the projectile sigma(q,q-p)(r) are presented for the systems Xeq+-B, B=He, Ar, and Xe (15 less than or equal to q less than or equal to 43). The results are also describe d in terms of electron-retainment (sigma(q,q-p)) electron-removal (sig ma(q)(r)), and total-reaction (sigma(q)) cross sections. Further, we d educe experimental single-electron-capture cross sections sigma(q-1,q- 2)(1) for Xe(q-1+)-B collisions from measurements on the Xeq+-B system . The data are compared with earlier and more recent scaling laws and the extended classical over-the-barrier model. [S1050-2947(97)08511-9] .
