Set up of a short magnetic lens electron spectrometer and investigation of cesium-137 and thulium-170 decay.
Abstract
dc:descriptionThe present work contains the discussion on the set up of a short magnetic lens electron spectrometer, and the results of an investigation of the beta decay spectra of Cs137 and Tm170. A short magnetic lens electron spectrometer of about 21cm focal length was set up and used during the course of this investigation. A Cs137 source was mainly used as a calibration source since decay spectrum is well understood. The magnetic field was varied in the range such that the electrons of 400 to 5200 gauss cm in momentum can be focused. The spectrometer resolution of 2.16% at the K peak of Cs 137 (624.2 KeV) and the counter resolution of 31.3% is attained. Beta decay spectra and conversion electrons of Cs137 and Tm 170 were studied. Fermi-Kurie plots of Cs137 and Tm 170 are presented.
