A new electron detector array, designed for use with large gamma detector systems, has been constructed. This new array consists of up to six mini-orange spectrometers, combining high efficiency with excellent background rejection. The array was used to detect internal conversion electrons from the decay of high spin states in [sup 130]Ce. A surplus electron yield in the continuum, above the predicted yield for E2 and M1 multipolarities, has been observed. It is postulated that this surplus consists of electric monopole (E0) transitions between bands of different deformations in the [sup 130]Ce continuum. Estimates have been made, based on the experimental results, of E0 transition matrix elements for the surplus. These estimates agree in magnitude with known matrix elements for discrete E0 transitions in nearby nuclei.
