Abstract
Three semi-circular focusing spectrometers, making use of a common magnetic field, have been used to measure the angular correlation of the internal conversion electron pairs produced in the decay of the 1·85 MeV state of 88Sr. The results support the assignment 2+ for this state. Similar equipment has been used to measure the angular correlation of certain conversion electron cascades. With a polarimeter having good energy resolution, direction–polarization measurements have been carried out on the 0·90, 1·85 MeV gamma-ray cascade in 88Sr. These show that the 1·85 and 2·75 MeV levels in this nucleus have even and odd parity respectively.
