Abstract
The low-Q Re-187 forbidden bets transition is studied by means of a microbo lometers array in order to get a direct limit on the <(nu)over bar>(e) mass . The achievable limit of the on-the-shelf small array (ten detectors) in o ne year measure acquisition time is less than 10eV/c(2). Silicon and German ium thermistors are being developed also for high resolution x-ray spectros copy; an excellent energy resolution of 5.4eV in the 6keV region has been a chieved. This represent the best published result of an Energy Dispersive S ensor (EDS) in this spectral band.
