The flux-weighted average cross sections of ) reactions and isomeric yield ratios of
,
, and
were measured with the bremsstrahlung end-point energies of 50, 60, and 70 MeV using an activation and off-line
-ray spectrometric technique at the Pohang Accelerator Laboratory (PAL), Korea. It was observed that the average cross sections of the
reactions increase with bremsstrahlung energy up to the Gaint Dipole Resonance (GDR) region. Thereafter, it shows a small decrease trend with bremsstrahlung energy due to the opening of another reaction channel. The isomeric yield ratios of same product in the
, (n,2n), (p,x), (
, and
reactions for various targets show that the spin of the target nucleus plays a vital role besides the effect of excitation energy and input angular momentum in determining the isomeric yield ratios.
