We present a systematic study of spherically symmetric self-dual solutions of
SU(2) Yang-Mills theory on Euclidean Schwarzschild space. All the previously
known solutions are recovered and a new one-parameter family of instantons is
obtained. The newly found solutions have continuous actions and interpolate
between the classic Charap and Duff instantons. We examine the physical
properties of this family and show that it consists of dyons of unit (magnetic
and electric) charge.Comment: 12 pages, 5 figures. To appear in Phys Rev
