The author wishes to correct the estimates of t. and V and two misprints.

(1) In equation (3), one should read - ir2(

. In equation (12), the denominator reads(1) In equation (3), one should read - V . In equation (12), the denominator reads
if, in relation (7), 2 kB T, is more properly replaced by the corresponding gap
8 n = 3.4 kB Tn. From these equations, one deduces T,!--- 40 K for V/4 tll = 0.3 if t.l/tll t_ 10- 2. Thus
ti = 8 x 10- 3 ev -- 2 kB T2, where T2 ==! 60 K.
(2) A rough estimate of tl /tp is deduced from the anisotropy of resistivity. Equation (20) should read
where a , and all are the respective CuCu distances. Factor 2 takes into account the van Hove singularity,
with vanishing electron speed parallel to the planes. Then t, ltll =...! 2 x 10- 2, in approximate agreement with the previous assumption.
