The Study of Isomeric Ratios in Photonuclear Reactions Forming High Spin Isomers in the Giant Dipole Resonance Region
Abstract
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.
