We studied the isomeric ratios  in  odd-odd nuclei \(^{196}\)Au,\(^{182}\)Ta  and \(^{194}\)Ir  with    high spin isomeric states  produced  in \(^{197}\)Au\((\gamma,  n)\) \(^{196m,g}\)Au, \(^{183}\)W\((\gamma,  p)\) \(^{182m,g}\)Ta  and \(^{185}\)Pt\((\gamma,  p)\)\(^{194m,g}\)Ir  reactions  by  using  the activation  technique  and  \(\gamma\)-ray  spectroscopic  method  in  the  giant    dipole  resonance  (GDR)  region.  The high-purity natural Au, W and Pt  foils in disc shape were irradiated with bremsstrahlungs  generated from an  electron  accelerator  Microtron.  The  irradiated  foils  were  measured  by  the  high  resolution  \(\gamma\)-ray spectroscopic system which consists of a Ge(HP) detector and a multichannel analyzer. In order to improve the  accuracy  of  the  experimental  results,  necessary  corrections  were  made  in  the  \(\gamma\)-ray  activity measurements and data analysis.  The results were  analyzed,  discussed and compared with those of other authors  as well as with theoretical model calculations.  The study shows that the isomeric ratios in  nuclei with high spin isomeric states are much lower than that in low spin isomeric state isomers.

Fission Neutrons

Mictrorons are accelerators of electrons and are simultaneous sources of bremsstrahlung photon flux and fission neutrons. In 1982, a microtron of seventeen trajectories Microtron MT - 17 was put into operation at the National Institute of Physics of Vietnam. Though very modest, microtons are very useful for developing countries such as Vietnam in both fundamental and applied physics research. During the recent years by using the above mentioned MT - 17 and microtrons from other institutes we have carried out different investigations. In this report we present some results obtained in the studies of photonuclear reactions and photon activation analysis in the giant dipole resonance region.
