Abstract

The quadrupole moments of the first excited 2 + states in 9 6 3 'Oo3

Quadrupole moments of some doubly-even molibden nuclei and the onset of collectivity

“…The calculated Q(2 + ) (IBM-1 and IBM-2) results of Mo isotopes are compared with some previous experimental [12][13][14] ones along with the data of neighboring Ru [15] Recently, an amount of many light isotopes around the mass region A ∼ = 100 have been checked out by being stressed primarily on explaining the energy spectra and transition probabilities. But the number of this kind of investigations for the quadrupole moment is not enough even though it is one of the most important observables to probe changes in nuclear shapes.…”

“…So, the introductory part of this paper contains an outline as follows; a theoretical background of IBM-1 and IBM-2 Hamiltonians is given in Section 2. The calculated results of the present study are compared with some previous experimental [11][12][13][14][15] data in Section 3. The usual features and the calculated quadrupole moments of 94,96,98,100,102,104,106,108 Mo nuclei are also reviewed in the same section.…”

“…Moreover, Q(2 + 1 ) values given in Fig. 4 are also compared to the ones of neighboring Ru [15] isotopes in Table 4.…”

“…For the cross-section of the 2 + level, the term P3 =Moi~2~ M2[21 Mzlo~ is of importance. Experience [14,28,29] shows that the sign of this term is negative (in the convention of the de Boer-Winther code) in this mass-region, and the data were evaluated under this assumption. The con- a The B(E2) value has been taken from [26] for normalization b In [27], an upper limit of < 1 ~o for M 1 admixture has been given for this transition.…”
