Nuclear Gamma-Radiation of Cu61


The positron spectrum of Cu61 has been examined recently by Cook and Langer with a large magnetic spectrometer. The experimental curves of these authors show a deviation from the Fermi distribution which is much larger than for Cu64 and it seems possible that not all of this deviation arises from the instrumental factors. It is pointed out by different authors that Cu61 does not emit nuclear gamma-rays which means that the spectrum of Cu61 must be simple. On the other hand the measurements of Cook and Langer can hardly be understood without the assumption of a complex spectrum. To examine this discrepancy, we started a search for gamma-radiation in Cu61.
