Magnetic multipole transitions of a stripped carbon ion in a variety of Debye plasmas

Survival of the excited triplet states and the spin-forbidden transitions including the magnetic dipole (M1) and magnetic quadrupole (M2) decays in the two-electron ion embedded in a variety of Debye plasmas are investigated theoretically. The dependence of the transition energy on the plasmas screening strength exhibits remarkably opposite patterns for the principal quantum number conserving and the non-conserving transitions. The magnetic multipole decay rates of the lower-lying states are seen to remain less affected at lower values of the screening magnitude.
