Abstract

A shell model analysis of the interaction between configurations of protons in the $2 p_{12}$ and $1 g_{92}$ orbits is presented. Matrix elements of the effective interaction are determined which accurately reproduce a larger number of experimental data. These are binding energies and positions of excited states in Zr⁹⁰, Nb⁹¹, Mo⁹² and Tc⁹³. The interaction of a $2 d_{52}$ neutron with $2 p_{12}$ and $1 g_{92}$ protons is determined form the levels of Y⁹⁰ and Nb⁹². This interaction is used to calculate the spectra of nuclei with protons in the $2 P_{12−1g_{92}}$ shell and neutrons in the $2 d_{5/2}$ orbit. Good agreement is obtained between calculated and experimental energies. In particular, the calculated energy of the isomeric state in Mo⁹³ and the energies in the following cascade agree very well with the experimental energies.

Nuclear data sheets for A = 91
2013, Nuclear Data Sheets
Experimental nuclear structure and decay data for all known A=91 nuclides (As, Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd) have been evaluated. This evaluation, covering data received by 1 September 2013, supersedes the 1998 evaluation by C. M. Baglin published in Nuclear Data Sheets 86, 1 (1999) (15 December 1998 literature cutoff), and subsequent evaluations by C. M. Baglin added to the ENSDF database for Kr, Sr and Zr (29 December 2000 literature cutoff) and by B. Singh for ⁹¹Tc (6 November 2000 literature cutoff).
The structure of 100Sn and neighbouring nuclei
2013, Progress in Particle and Nuclear Physics
The nuclear structure in the ¹⁰⁰Sn region is reviewed. State-of-the-art experimental techniques involving stable and radioactive beam facilities have enabled access to exotic nuclei in its next neighbourhood. The analysis of experimental data has established the shell structure and its evolution towards $N = Z = 50$ , seniority conservation and proton–neutron interaction in the g_9/2 orbit, the super-allowed Gamow–Teller decay of ¹⁰⁰Sn, masses and half lives along the $r p$ -path, and super-allowed $α$ decay beyond ¹⁰⁰Sn. The status of theoretical approaches in shell model and mean-field investigations is described and their predictive power assessed. Structure features of ¹⁰⁰Sn and its doubly-magic neighbours ⁵⁶Ni at $N = Z$ , ¹³²Sn and ⁷⁸Ni at $N ≫ Z$ are compared. An outlook is given on future developments of experimental and theoretical methods.
Study of the low-lying collective states in 94-100Mo isotopes using the MAVA
2006, Nuclear Physics A
A systematic investigation of reduced electric quadrupole decay strengths, $B (E 2)$ and level energies of even ^94–100Mo isotopes is performed using the microscopic anharmonic vibrator approach (MAVA). The MAVA is suited for dynamical microscopic description of two-phonon-like states and their energy splitting due to interaction with low-lying one-phonon states. The starting point for the model is a realistic single-particle valence space and a microscopic many-body Hamiltonian which is used to generate the one-phonon states by the use of the quasiparticle random-phase approximation (QRPA). The same Hamiltonian generates also the interaction between the one- and two-phonon states. Comparison of the calculated energies and $B (E 2)$ values with the available data suggests that ^94–100Mo are closer to anharmonic vibrators than deformed rotors.
Competition between proton and neutron excitations in 96Zr
2003, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The g factors of the 2⁺₁ and 3⁻₁ states in ⁹⁶Zr have been measured for the first time by Coulomb excitation of ⁹⁶Zr beams in inverse kinematics using transient magnetic fields. The resulting g factors are g(2⁺₁)=+0.03(7) and g(3⁻₁)=+0.98(15). The lifetime of the 2⁺₁ state, τ=0.82(10) ps, was redetermined via the Doppler Shift Attenuation Method. The 2⁺₁→0⁺₁ transition rate and the g-factor data are in fair agreement with shell-model calculations involving both proton and neutron excitations. The pronounced octupole strength of the 3⁻₁→0⁺₁ transition is not seen in the g factor which exceeds significantly an expected Z/A value.
