The multiplicity of KX-rays originating from the conversion of quasi-continuum transitions feeding non-collective discrete states in 143Eu was determined to be about 0.2 per cascade. This implies that the contribution of M1 transitions to the quasi-continuum is much larger than usually expected, possibly as a result of the presence of highly collective M1 bands in this nucleus. Alternatively, this may be a signature of the presence of E0 transitions. Much lower values of the multiplicity of KX-rays were measured for the quasi-continuum transitions feeding a strong E2 cascade in the same nucleus.
