✦ Synopsis

To get accurate values of the London penetration depths in YBa2CusOt, pSR measurements were performed on a high quality, sintered sample and a c-axls-oriented polycrystaL For the sintered sample the temperature dependence of the effective penetration depth Ae/y is well described by the two-fluid model, with AtH(0) ----155(10) nm. This behavior of A~jI(T) is consistent with conventional s-wave pairing. The anisotropy ratio A~/A~,b ~--5(1) was determined from measurements on the polycrystal. These results were
