✦ Synopsis

The laser produced carbon plasma in different regions of a curved magnetic field has been studied by emission spectroscopy. In addition to the ionic transitions CII, CIII, CIV; C Swan bands are observed. The intensity of the C Swan 2 2

band is greatly enhanced when the magnetic field lines are convex to the moving plasma with the positive field gradient. The observed change in emission characteristics is attributed to the recombination of electrons due to the curvature gradient drift of the magnetic field.
