Abstract
We observe vortex pinning in 2.2 GeV Au-ion irradiated NbSe2 by scanni ng tunneling microscopy (STM) at 3K. The ion irradiation generates col umnar defects which act as pinning sites. At various external magnetic fields the vortex arrangement is clearly resolved but shows strong di stortion. The location of individual defects is extracted from STM dat a and compared to the vortex arrangement.
