Abstract

The ¹⁰³Ag nucleus has been studied using the ¹⁰³Rh(α, 4nγ)¹⁰³Ag and ¹⁰³Rh(³He, 3nγ)¹⁰³Ag reactions. A set of standard in-beam measurements involving relative excitation function measurements of γ-rays, γ-γ-Δt coincidences, conversion electron measurements and angular distribution and linear polarization measurements of emitted γ-rays have been performed. Excited states with spin values up to $272$ are populated in this nucleus. Among these excitations a positive-parity band built on the $J^{π} = 72^{+} or 92^{+}$ state can be distinguished. This band has similar properties as the band observed in ¹⁰⁵Ag. The experimental data on the band in ^{103, 105}Ag are compared to the prediction of the Nilsson model with Coriolis coupling at intermediate deformation ε = 0.10−0.15. Energy levels of the positive-parity bands are reproduced satisfactorily by the calculations assuming either a $K = 72^{+} [413] or K = 92^{+} [404]$ band head. However, electromagnetic properties of the levels, branching and mixing ratios, are better reproduced when assuming the $K = 72^{+}$ band head. Attenuation of the Coriolis interaction was introduced in order to improve the fit of the calculated energies of the levels to the experimental values.

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.
Nuclear data sheets for A = 103

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.
Coexistence in odd-mass nuclei
1983, Physics Reports
Shape coexistence in odd-mass nuclei near closed shells (±1 and ±3 nucleons) is reviewed. Two main approaches are presented. The more historical one starts from the explicit introduction of a deformation degree of freedom and allows particular Nilsson orbitals to occur very low in excitation energy. A second approach starts from spherical particle-hole (p-h) excitations across a closed shell and allows interactions with quadrupole vibrations of the underlying core nucleus. The equivalence between the two approaches is discussed in some detail. Attention is given also to other approaches to the description of coexistence. A detailed review of the experimental evidence for coexistence in odd-mass nuclei near the Z = 28, 50, 82 and N = 28, 50, 82 closed shells is made. In addition, the fingerprints of coexisting states, i.e. the most pronounced nuclear structure properties characterizing such states, are presented. These fingerprints provide a necessary (though not sufficient) set of conditions for identifying coexistence throughout the nuclear mass table. At the end, we briefly describe the connection of the present study to other areas of nuclear structure such as related configurations in doubly-even nuclei, many-particle many-hole excitations, deep-lying hole states, and the possibility of incorporating these degrees of freedom into an Interacting Boson Approximation (IBA) framework. A major conclusion of this review is that there is a clear connection between shape coexistence and shell-model intruder states. A variety of topics is suggested for future experimental and theoretical investigation.
Gamma-ray spectroscopic study of <sup>101</sup>Ag
1980, Nuclear Physics A
Excited states in ¹⁰¹Ag have been investigated using the ¹⁰²Pd(p, 2nγ), ⁹²Mo(¹²C, p2nγ) and the ¹⁰²Pd(³He, p3nγ) reactions and employing standard γ-ray spectroscopic techniques. In addition to the known negative-parity multiplet structure built on top of the $12^{−}$ isomeric state, a set of 17 new levels was found presumably with positive parity. Definite spin and parity assignments in the range of $112^{+} − 232^{+}$ could be made for 7 levels and tentative assignments for 5 levels. All these levels decay subsequently to the $92^{+}$ ground state. A comparison of the level structure and decay properties of the ^101–107Ag isotopes reveals a distinct decrease of collectivity in the approach towards the closed N = 50 shell.
