Abstract

The ¹⁰²Mo activity was obtained by photofission of natural U and thermal-neutron induced fission of ²³⁵U, with subsequent chemical separation of the molybdenum fraction. In addition, nuclei with mass 102 were separated from fission products of ²³⁵U(n_th, f) using the mass separator LOHENGRIN. A decay scheme and absolute γ-intensities are deduced from measured γ-ray, X-ray and γ-coincidence spectra. Logftvalues are calculated. Shell-model calculations for a $(πlg_{92})^{3}$ $(νlg_{72})^{3}$ multiplet have been carried out using effective nucleon-nucleon interactions. The γ-decay between low-lying, low-spin members of this multiplet was studied in detail and compared with the experimental data.

Nuclear Data Sheets for A = 102
2009, Nuclear Data Sheets
The 1998 evaluation on mass A = 102 (1998De15) has been revised, taking into account all data available before december 2008. Detailed experimental information is presented from the neutron rich nucleus ¹⁰²Rb to the neutron deficient ¹⁰²Sn nucleus. No information on excited states of ¹⁰²Rb is available and very scarce for ¹⁰²Sr Especially new (HI,xnγ) data sets for several nuclides have been evaluated and new and more accurate data for γ intensities and multipolarities obtained. For ¹⁰²Ru very precise new data of the Budapest (n,γ) collaboration have been included.A new and very elaborated decay scheme for ¹⁰²In is obtained. Isomerism in ¹⁰²Y and ¹⁰²Nb needs further investigation due to conflicting results.

The 1976 evaluation on mass A=102 has been reviewed, considering all experimental data available before March 1982. Information is presented from the very neutron-rich ¹⁰²Rb to the neutron-deficient ¹⁰²In.
The knowledge of β decay schemes is extended considerably for the neutron-rich isotopes, by new investigations on the decay of the ¹⁰²Nb isomers, ¹⁰²Mo and ¹⁰²Tc (5.28 s). For the two stable isotopes ¹⁰²Ru and ¹⁰²Pd, Coulomb excitation was studied extensively, although some discrepancies remain. From many other reactions, valuable new information was obtained, especially for ¹⁰²Pd and ¹⁰²Cd. However, the information on the ¹⁰²Rh level scheme remains rather scarce.
Theoretical studies on different properties of A=102 nuclei are reported in the adopted levels data sets.
