From complex multiplication we know that elliptic units are contained in certain ray class fields over a quadratic imaginary number field , and Ramachandra [3] has shown that these ray class fields can even be generated by elliptic units. However the generators constructed by Ramachandra involve very complicated products of high powers of singular values of the Klein form defined below and singular values of the discriminant . It is the aim of this paper to show, that in many cases...
