S. Moriyama et M. Minowa, THE 17-KEV NEUTRINO AND THE SEARCH FOR ANOMALOUS GAMMA-RAYS IN S-35 DECAY, Physics letters. Section B, 347(1-2), 1995, pp. 152-157
We searched for anomalous gamma rays in S-35 decay as a possible expla
nation for the kink in the beta-decay spectrum, which is claimed to be
due to the emission of the heavy 17 keV neutrino. The intensity and s
pectrum of gamma rays we observed are consistent with those of the ext
ernal and internal bremsstrahlung of the beta rays. It is concluded th
at the gamma-ray spectrum has no structures which may mimic the claime
d kink.
