- Abstract
- We measured the flux-weighted average cross-sections and the isomeric yield ratios of Rh-99m,Rh- g,Rh- 100m,Rh- g,Rh- 101m,Rh- g,Rh- 102m,Rh- g in the Rh-103(, xn) reactions with the bremsstrahlung end-point energies of 55 and 60MeV by the activation and the off-line -ray spectrometric technique, using the 100MeV electron linac at the Pohang Accelerator Laboratory (PAL), Korea. The flux-weighted average cross-sections were calculated by using the computer code TALYS 1.6 based on mono-energetic photons, and compared with the present experimental data. The flux-weighted average cross-sections of Rh-103(, xn) reactions in intermediate bremsstrahlung energies are the first time measurement and are found to increase from their threshold value to a particular value, where the other reaction channels open up. Thereafter, it decreases with bremsstrahlung energy due to its partition in different reaction channels. The isomeric yield ratios (IR) of Rh-99m,Rh- g,Rh- 100m,Rh- g,Rh- 101m,Rh- g,Rh- 102m,Rh- g in the Rh-103(, xn) reactions from the present work were compared with the literature data in the Rh-103(d, x), Ru102-99(p, x) , Rh-103(,n) , Rh-103(, 2p3n) , Ru-102(He-3, x), and Rh-103(, xn) reactions. It was found that the IR values of Rh-102,Rh- 101,Rh- 100,Rh- 99 in all these reactions increase with the projectile energy, which indicates the role of excitation energy. At the same excitation energy, the IR values of Rh-102,Rh- 101,Rh- 100,Rh- 99 are higher in the charged particle-induced reactions than in the photon-induced reaction, which indicates the role of input angular momentum.
