DESCRIPTION:Speakers: Abraham Avaa (iThemba/Wits)\nMonopole transition stu
 dies has been of theoretical and experimental interest for over 50 years n
 ow. Since gamma decay is forbidden between two 0+ states\, the study of nu
 clear structure through the usual technique of gamma measurement cannot be
  useful in such a case. Hence\, the decay mode of spin zero state is most 
 probable by electron emission. Depending on the probable transition energi
 es\, this can be achieved through either internal conversion or by interna
 l pair formation. Therefore\, measurement of electrons is crucial for E0 s
 tudies. \nIn order to implement E0 studies at iThemba labs\, an electron s
 pectrometer has been refurbished and characterised using calibration sourc
 es of internal conversion electrons (ICE): 133Ba and 207Bi. The results of
  the spectrometer characteristics are described.  The spectrometer coupled
  with an array of fast timing detectors and Low energy photon spectrometer
  (LEPS) was successfully implemented for in-beam experiment. \nPreliminary
  result will be presented for the measured conversion coefficient and mono
 pole strength parameter in 72Ge and 72Se determined from electron-gamma co
 incident experiments from 70Ge(α\,α') reaction.\n\nhttps://indico.tlabs.
