Abstract

The scattering of fast neutrons from ¹⁰³Rh was studied by means of (n, n), (n, n′) and (n, n′γ) measurements at neutron energies up to 2 MeV. More than fifty unknown γ-transitions were identified and a level scheme established which includes fifteen unreported excited states. Branching ratios, spins and parities for these levels were deduced, as well as the effective activation cross sections for the ¹⁰³Rh(n, n′)^103mRh reaction. The results are compared with existing data and with calculations based on the optical and statistical models.

Nuclear Data Sheets for A = 103
2009, Nuclear Data Sheets
The 2001 evaluation on mass A = 103 (2001De37) has been revised, taking into account all data available before March 2009. Experimental information is presented from the neutron rich nucleus ¹⁰³Sr to the neutron deficient ¹⁰³Sn nucleus. The experimental information on excited states for ¹⁰³Sr and ¹⁰³y is very scarce New (HI, xnγ) data sets for several nuclides have been evaluated and new and more accurate data for γ intensities and multipolarities obtained. The BRICC code has been used for the calculation of conversion coefficients.
Model calculations of excitation functions of neutron-induced reactions on Rh
1995, Annals of Nuclear Energy
Cross sections of neutron-induced reactions on ¹⁰³Rh have been calculated by means of the statistical model and the coupled-channels optical model for incident-neutron energies up to 30 MeV. The incentive for this study was a new measurement of the ¹⁰³Rh(n,n′)^103mRh cross section which will—together with the present calculations—enter into a dosimetry-reaction evaluation. The validation of the model parameters relied on nuclear-structure data as far as possible. Apart from the ¹⁰³Rh(n,n′)^103mRh excitation function also those for the $^{103} Rh (n, 2n)^{102m,g,(m + g)} Rh,^{103} Rh (n, 3n)^{101m,(m + g)} Rh,^{103} Rh (n, p)^{103} Ru and^{103} Rh (n, α)^{100} Tc$ reactions were calculated.

Photonuclear excitation of <sup>103</sup>Rh by synchrotron radiation
1989, International Journal of Radiation Applications and Instrumentation. Part
Photonuclear excitation of the ¹⁰³Rh nucleus was studied using synchrotron radiation. Formation of the excited state was confirmed by observing K x-rays emitted following the isomeric transition of ^103mRh with a low-energy photon spectrometer. The intensity of induced activity due to ¹⁰³Rh(γ, γ′)^103mRh reaction was determined carefully by subtracting the fluorescent K x-rays due to natural background radiation. The integral cross-section for isomer production of ^103mRh by resonance absorption of photons at 295 keV is found to be (2.1 ± 0.8) × 10⁻²⁸ cm² eV and is compared with that estimated from the previous experimental value for the 1277-keV level.

Experimental information is presented from the neutron rich ¹⁰³Zr to the neutron deficient ¹⁰³Sn. At the neutron rich side, new information on the β⁻ decay of ¹⁰³Zr (1.3 s), ¹⁰³Nb (1.5 s) and ¹⁰³Mo (67.5 s) is presented. From (n,γ) studies, very elaborate level and γ information in ¹⁰³Ru was obtained. The excited states of ¹⁰³Ru have been studied via ¹⁰²Ru(d,p) and ¹⁰⁴Ru(d,t) experiments. The β⁻ decay of ¹⁰³Ru (39.26 d) was studied extensively while the ¹⁰³Ag ε decay was also reinvestigated. Excited states of ¹⁰³Pd were studied via ¹⁰⁴Pd(d,t),(³He,α). The ¹⁰³Cd ε decay (7.3 min) has been investigated by several groups. (HI,xnypγ) reactions were used in the study of the high spin states in ¹⁰³Ag. For the first time, experimental information is shown for the decay of ¹⁰³In (65 s). Theoretical studies on different properties of A=103 nuclei are reported in the adopted levels tables.
