Bg. Lindsay et al., CHARGE-TRANSFER OF 0.5-, 1.5-, AND 5-KEV PROTONS WITH ATOMIC OXYGEN -ABSOLUTE DIFFERENTIAL AND INTEGRAL CROSS-SECTIONS, Physical review. A, 53(1), 1996, pp. 212-218
We report measurements of the absolute differential cross sections for
charge-transfer scattering of 0.5-, 1.5-, and 5-keV protons by atomic
oxygen at scattering angles between 0.01(0) and 2.6(0) in the laborat
ory frame. Absolute integral cross sections are also reported and comp
ared with previously published total cross sections. The measurements
were made using a flowing gas target, which consisted of a mixture of
atomic and molecular oxygen produced by passage of O-2 through a micro
wave discharge. The cross sections for atomic oxygen were obtained by
appropriate subtraction of the signal due to molecular oxygen from tha
t due to the mixture of O and O-2.
