Abstract

[Formula Presented] Be electron capture decay to [Formula Presented] Li has been investigated by means of a cryogenic [Formula Presented] calorimeter. A cryogenic particle detector, due to its low energy threshold and good energy resolution, allows us to detect for the first time the complete [Formula Presented] Be calorimetric energy spectrum with a peak width of 24 eV full width at half maximum at 112 eV. The observed decrease in the rate of the absorber activity corresponds to the expected [Formula Presented] Be half-life of 53 days. This kind of detector has an important application in the environment of a lithium radiochemical solar neutrino experiment which is in progress in Moscow. A discussion about the possible processes which take place inside the BeO absorber during the energy thermalization is reported.
