摘要：

The pinning by columnar defects produced by 1.0 GeV U ion bombardment along the c-axis of an untwinned YBa2Cu3O7 single crystal is characterized. The accommodation angle is nearly 90 degrees at low field, the resistivity anisotropy is reversed, and the onset of pinning occurs well into the fluctuation regime. The anisotropy and strength of the pinning are compared to that of twin boundaries.
