Π State

We used the multichannel quantum defect theory to compute cross sections and rate coefficients for the dissociative recombination of CH + initially in its lowest vibrational level v i + = 0 with electrons of incident energy below 0.2 eV. We have focused on the contribution of the 2 2 Π state which is the main dissociative recombination route at low collision energies. The final cross section is obtained by averaging the relevant initial rotational states ( N i + = 0 , ⋯ , 10 ) with a 300 K Boltzmann distribution. The Maxwell isotropic rate coefficients for dissociative recombination are also calculated for different initial rotational states and for electronic temperatures up to a few hundred Kelvins. Our results are compared to storage-ring measurements.

Correct Calculation

New measurements of the differential cross section have been carried out in the reaction 9Be(3He, p)11B between 13.0- and 14.2-MeV incident energy. In order to compute the effective analyzing powers of polarimeters used to measure proton polarization in the same reaction, a precise knowledge of angular variations is necessary. The achieved accuracy allows a correct calculation of the false asymmetry caused by nonuniform illumination of the analyser from cross section variations.
