Full text access: Open
Part I. A number of modifications were made to the large spheroidal field B-spectrometer and a small lens spectrometer was attachedto it for 3-3 coincidence measurements. The method of ion ejection from a capillary tube for preparing thin sources was developed and used for making Ce144 sources. An attemptwas made to verify the existence of a 166 keV excited statein Pr 144 suggested by some investigators by observing the predicted Y-Y cascade, i.e. 33 keV Y-ray followed by a 133 keV Y-ray. No evidence of B-B coincidences between the K133 and L133 conversion lines was found. Part II. The trajectories of electrons in a spheroidal field were found by integrating the equations of motion using the electronic computer 'Mercury' of the University of London. The focusing properties of a B-spectrometer using this field were investigated and an attempt was made to find an analytical form for the field intensity which would describe the field in the large spectrometer.
