摘要：

The Stark broadening of a Be II line (1s(2)3d D-2 - 1s(2)4f F-2, 467.339 nm) under a magnetic field is evaluated with the divertor plasma of ITER in mind. The electron and ion perturbers are treated in the impact and static approximations, respectively. The perturbation term due to the magnetic field is included in the static approximation. The results show that the Stark broadening comes to be significantly large when the density is higher than 1(021 )m(-3), and the ion temperature would be overestimated if the Stark broadening is not taken into account.
