Distribution and Kinematics of H i through Raman He ii Spectroscopy of NGC 6302
The young planetary nebula NGC 6302 is known to exhibit Raman-scattered He ii features at 6545 Å and 4851 Å. These features are formed through inelastic scattering of He ii λλ 1025 and 972 with hydrogen atoms in the ground state, for which the cross sections are 1.2 × 10 ^−21 cm ^2 and 1.4 × 10 ^−22...
