Abstract
The Bose-glass transition field B-BG in YBa2Cu3O7 single crystals with columnar defects is tracked by the onset of the third harmonic genera tion. The progressive upward shift of the B-BG(T)-line with the irradi ation dose is followed by a saturation for the matching fields B-phi=2 0 kG - 100 kG. The uppermost position of the Bose-glass transition is interpreted as a boundary between entangled and disentangled vortex Li quids in virgin YBa2CU3O7.
