“…The ground state of 69As was assigned a tentative J~=5/2 in the work of Muszynski and Mark [1] on the basis of its decay properties and nuclear systematics. The J~ assignments of 5/2-, 1/2-, 3/2 and 3/2-for these states, respectively, have been confirmed by nuclear reaction works [-2, 3, 8] and inbeam spectroscopy works [4,6,7]. The results of the present experiment on the ground state, 86.79, 232.73 and 374.1keV states in 69Ge, though more precise are in general agreement with those of Ref.…”

“…The J~ assignments of 5/2-, 1/2-, 3/2 and 3/2-for these states, respectively, have been confirmed by nuclear reaction works [-2, 3, 8] and inbeam spectroscopy works [4,6,7]. Subsequently, the state has been reported in several other works [3][4][5][6], with similar conclusions. The results of nuclear reaction works indicate that the ground state, 86.79 and 374.1 keV states in 69Ge contain substantial single neutron components of lf5/2, 2pl/2 and 2p3/2 orbitals, respectively, in their wave functions.…”

The beta decay of 69As is reinvestigated. Its decay half-life is measured to be 15.1 _+0.3 m. Using beta, gamma and conversion electron spectroscopy techniques, a decay scheme comprising 68 transitions among 28 excited states in ('9Ge is proposed. Spin-parity assignments are made to many states and B(M1) and B(E2) are deduced for some transitions. The structure thus obtained for 69Ge is compared with that from other works and discussed in the light of nuclear models.

Central artery stiffness has emerged over the past 15 years as a clinically significant indicator of cardiovascular function and initiator of disease. Loss of elastic fiber integrity is one of the primary contributors to increased arterial stiffening in aging, hypertension, and related conditions. Elastic fibers consist of an elastin core and multiple glycoproteins; hence defects in any of these constituents can adversely affect arterial wall mechanics. In this paper, we focus on mechanical consequences of the loss of fibulin-5, an elastin-associated glycoprotein involved in elastogenesis. Specifically, we compared the biaxial mechanical properties of five central arteries-the ascending thoracic aorta, descending thoracic aorta, suprarenal abdominal aorta, infrarenal abdominal aorta, and common carotid artery-from male and female wild-type and fibulin-5 deficient mice. Results revealed that, independent of sex, all five regions in the fibulin-5 deficient mice manifested a marked increase in structural stiffness but also a marked decrease in elastic energy storage and typically an increase in energy dissipation, with all differences being most dramatic in the ascending and abdominal aortas. Given that the primary function of large arteries is to store elastic energy during systole and to use this energy during diastole to work on the blood, fibulin-5 deficiency results in a widespread diminishment of central artery function that can have significant effects on hemodynamics and cardiac function.

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.
