Phys. Rev. A 57, 3598–3602 (1998)Temperature-dependent depolarization cross sections of the 5d6p 3P1 and 3D1 states of laser-ablated Ba in He gas in the range 10–300 KReceived 3 December 1997; published in the issue dated May 1998 We have applied the laser-ablation technique for the study of depolarization effects of the 5d6p 3P1 and 3D1 states of Ba with He gas in the wide temperature range of 10–300 K. The depolarization cross sections of both states have been found to have a positive temperature dependence, indicating that the responsible interaction is not a van der Waals type. A tentative and qualitative explanation for the difference of the temperature dependence between 5d6p 3P1 and 3D1 is given in terms of electron density distribution. © 1998 The American Physical Society URL:
