Eur. Phys. J. A (2012) 48: 89
The ROSEBUD Collaboration has dedicated several underground runs to study different types
of bolometers, mainly for the search of dark matter. Some of these runs, profiting from the good energy
resolution of one bolometer of BGO and the ultra-low background of the underground laboratory of
Canfranc (LSC), allowed the measurement of the L/K electron capture ratio of the 207Bi decay to the
1633 keV level of 207Pb. This paper constitutes the first published measurement of this magnitude.
