Nuclear data sheets for A= 70

The doubly even isotopes of Zn and Ge have been investigated in a model in which two quasiparticle excitations, constructed in a (0f7/2), lp3/2, Ofs/2, lpl/2,099/2 configuration 4-0 56 space, are coupled with quadrupole vibrations of the core, viz. Ca or Ni. The 0f7/2 orbit is excluded in case of a 56Ni core. The spectra, except for low-lying excited 0 + states, could be reproduced reasonably well. The calculated E2 strengths and quadrupole moments are in fair agreement with experiment.

“…The calculated and experimental energy spectra of 7~ are compared with each other in Figure 7. The experimental spectrum is taken from the complication [55]. The 2.53-MeV level is taken from the 69Ga(3He, d) work [56] which restricted this level to The experimental levels up to 3 MeV are well reproduced by the present calculation.…”

Calculations of the energy spectra of Zn, Ga, and Ge isotopes by the shell model

The effective Hamiltonian which was determined empirically by Koops and Glaudemans is tested in shell model calculations for the nuclei in the full(1 P3/2,0]5/2, 1 Pl/J space. The resulting energy spectra are compared with the experimental spectra and results of previous calculations. The overall agreement with experiment is as satisfactory for these nuclei as for the Ni and Cu isotopes, by which the Hamiltonian was determined. It is noticed that the spectra of 67Zn and 67'69Ga calculated in this work are similar to those provided by the Alaga model.

“…The Stockholm group used 69Ga(d, p) at Ed = 7.1 MeV and 7'Zn(p, ny) at Ep = 3.5 MeV (Z. P. Sawa [5]) and direct reactions 69Ga(d, p), ' 1 Ga(d,t) and also y-ray techniques with 69Ga(d, py), 6'Zn(a, py), 70Zn(p, ny) and 69Ga(n, y) reactions (S. E. Arnell et al [6]), to give the first reliable level scheme of '°Ga up to 1.6 MeV excitation energy. All previous works have been summarized by K. R. Alvar et al [7]. The first spin assignments were done by M. R. Najam et al [8] by means of a y-ray study with the 7'Zn(p, ny) 70Ga reaction at Ep = 1.7-3.2 MeV.…”

High spin levels in 70Ga via 68Zn(α, pnγ) 70Ga

et al. 1977

View full text Add to dashboard Cite

The 70Ga nucleus has been investigated via the 68Zn(α, pnγ)70Ga reaction at Eα = 23-40 MeV. The level scheme has been established by means of relative yield functions, electronic timing measurements, prompt and delayed coincidences and angular distributions of the emitted γ rays. The assignations of spins up to 9+ to levels up to 2.9 MeV excitation energy specify the components of the (νlg9/2) subshell
