Abstract :
Experiments on creation of artificial ball lightning (BL) by capillary gas discharges at interaction of plasmas with a wire made of a Sn alloy have been undertaken. Two types of long-lived luminescent objects have been realized with sizes 1-5 mm and a lifetime of about 1 s. The first type is a solid metallic sphere and the second one is a sphere with a solid cover filled by a vapor. The obtained results confirm a model where a natural BL consists of a core filled by a vapor of fused material and a solid cover.
