(1) change

P dq2 in Eq. (29).

(2) the entries in column ‘‘P’’ in Table IV have to be sign reversed. With the column ‘‘P’’ sign reversed Table IV holds for the decays B_c ! M_cc  l_{ }

l.

(3) replace Table V by a new TableVgiven below.

(4) On page 11 (last paragraph) replace the sentence ‘‘For the decay into the other spin states one has A_FBe_{ }

A_FBe_{ but A}

therefore only list A_FBl_{ in the corrected Table V.}
