“…The (e-Ro) cross section a 13 (vI) were obtained from the phaseshifts of Yau etal (1979,1980) and were so normalised as to reporduce measurements (where available) of the scattering length A 1 (since for He, Ne and Ar the calculated scattering lengths were 13% lower, 11% lower and 40% higher than the respective measurements (cf Yau et al 1979(cf Yau et al , 1980). The first value in S the range o1 3 arising from (1-3) elastic collisions corresponds to 0' 1 3 = 41rA 1 at zero Table 1. Maximum cross sections (A 2 ) for Rb(1 5F)-rare-gas (no) collisions at 520 K based on the sum of (e-RG) elastic encounters with cross section a'0 and on (Rb*-RG) elastic encounters with cross section o2.…”

“…where jg 2 is the probability that the Rydberg electron has momentum k 1 , where 13 is " .the total cross section for all elastic and inelastic (1)(2)(3) collisions at relative speed V 13 and where V3 is the speed of the projectile A in the (A-Bk) centre-of-mass reference frame. This cross section (4) is an upper limit to any collision process satisfying specific criteria for the validity of the impulse approximation and states that the rate (V3o) for all A-B(n) elastic and inelastic processes is essentially limited to the total rate of free Rydberg e-A collisions.…”

“…A preliminary assessment based on the upper limits (5) and (15) can now be made. The table illustrates (5) and (15) for thermal (520 K) collisions of Rb(15F) with rare gases RG(He, Ne, Ar, Kr and Xe) for which vI >> v 3 . The (e-Ro) cross section a 13 (vI) were obtained from the phaseshifts of Yau etal (1979,1980) and were so normalised as to reporduce measurements (where available) of the scattering length A 1 (since for He, Ne and Ar the calculated scattering lengths were 13% lower, 11% lower and 40% higher than the respective measurements (cf Yau et al 1979(cf Yau et al , 1980).…”

“…at M k 'q a set of six equations, in general, or four for scatter-D CHANNELS ing in a plane, which must be solved simultaneously with 3 -3 .0 a coupled set (3). In order to relate the flux that flows Fthrough the incident area pdpdo to the scattering solid z…”

“…Note that Eq. (16) is equivalent to the homogeneous equation (16) with its right-hand side set equal to zero solved subject to a 3 …”
