Abstract

⁹⁷Pd has been obtained by the reaction ⁹⁶Ru(³He, 2n)⁹⁷Pd. Chemically separated samples from natural Ru targets showed that it decayed mostly to ^97gRh and gave absolute γ-yields. Direct γ-spectra, γ-γ and β-γ coincidences were measured on irradiated ⁹⁶Ru enriched targets. A Q_EC of 4.8 ± 0.3 MeV has been obtained. Of the 55 γ-transitions assigned to the decay of ⁹⁷Pd, 46 have been included in a level scheme.

Anomalous low-lying $72$ ⁺ and $52$ ⁺ states are found and compared to those of neighbouring isotopes. An attempt is made to explain these levels in the frame of the dressed 3QP model of Kuriyama et al.

Abstract: In this evaluation, the experimental data from a β-decay study of ⁹⁷Ag (1999Hu10), in combination with the data available from the previous evaluation (Agda Artna-Cohen, Nuclear Data Sheets 70, 85 (1993)), were used to assign excitation energies, β-decay branching ratios, logft values, spins and parities to states in ⁹⁷Pd. All γ transitions placed in the decay scheme of ⁹⁷Ag β decay were only accepted if at least the coincidence with 511 keV γ-quanta was observed and both of the connecting levels were confirmed by other γ transitions.
Nuclear Data Sheets Update for A = 97
1993, Nuclear Data Sheets
The experimental results leading to information about the level structure of nuclei with A=97 have been compiled and evaluated. These include the results of all experiments studying the decays within the mass chain as well as the reactions leading to nuclei with A=97. The compiled information is presented as data sets for the individual experiments. Based on all the relevant data sets, tables of adopted levels and γ radiations are then produced for each nucleus. This compilation replaces parts of "Nuclear Data Sheets for A=97" published in vol.46, p.607 (1985).
A high-speed target-rotation system (taro) for the study of short-lived nuclei
1986, Nuclear Inst. and Methods in Physics Research, A
We describe the design and performance of a high-speed target-rotation system for the study of nuclei far from stability, by which targets can be transported to the detector position in 60 ms after irradiation (90° rotation). The rotor movement and the cyclotron beam pulsing, as well as the data acquisition, are controlled by a microcomputer. Using this device $^{54} Co (T_{12} = 193 ms)$ and $^{58} Cu (T_{12} = 3.2 s)$ were observed in a test experiment with a transport efficiency of 71 and 98%, respectively (180° rotation).

Collective and shell-model excitations in <sup>97</sup><inf>45</inf>Rh<inf>52</inf>
1983, Nuclear Physics, Section A
⁹⁷Rh has been studied by deexcitation of the compound nucleus formed through the reactions ⁹⁶Ru(³He,pn) at 20 MeV and ⁹⁶Ru(²H,n) at 9 MeV. Direct γ-spectra, multidimensional γγ coincidences and angular distribution measurements lead to a proposed level scheme. These levels are compared to calculations based on the interacting boson-fermion approximation IBFA model in which the odd particle moves in the $1 g_{92}$ orbital. Evidence for the observation of shell-model states outside the sd boson configuration space in ⁹⁷Rh is obtained.
