The nuclear g factor of the first excited state in 106Pd has been measured by the method of perturbed angular correlations. The perturbing fields used were the internal fields on palladium in dilute iron and cobalt alloys. By comparing the rotation caused by these alloys with the rotation observed when nickel was the host, a measurement of the internal field on palladium in nickel has been obtained.The g factor of the first excited state in 106Pd has been determined to be +0.35 ± 0.03. The internal field on palladium in nickel at room temperature was found to be −174 ± 13 kOe.

Ions of 177Lu have been implanted in iron and nickel hosts at concentrations of about 1018/cm3. Perturbation of angular correlations in the gamma-ray cascade through the 113–keV level gives values for the internal fields on hafnium nuclei in these metals at room temperature and for this concentration of H(Fe) = −140 ± 10 kOe and H(Ni) = −60 ± 10 kOe. The rotation of the 250-keV level was also observed in the iron host. The nuclear g factor of this state is g = +0.26 ± 0.09.

A new europium complex, Eu (acac)3Aphen (where Hacac and Aphen stand for acetylacetone and 5-acrylamido-1,10-phenanthroline, respectively), was synthesized and characterized by elemental analysis, IR, UV and photoluminescence (PL) spectra. The ligand Aphen not only serves as an antenna ligand but also offers a functional group for polymer precursor. The room-temperature PL spectra of the europium (III) complex are composed of the typical Eu3+ red emission, assigned to transitions between the first excited state (5D0) and the multiplet (7F04). Compared to Eu (acac)2AA (where HAA is acrylic acid), Eu (acac)3Aphen exhibits greatly enhanced quantum efficiency (i.e., 14.1% vs 28.5%) and longer 5D0 lifetime (260 μs vs 568 μs).

ABSTRACTYtterbium (Yb) ions were co-implanted into Al0.70Ga0.30As:Er substrates at room temperature. The photoluminescence (PL) and PL lifetime were characterized. Co-implanted Yb3+ enhanced PL intensity of Er3+-related emission. Er3+-related main peak (1538.2 nm), in addition to Yb3+ dose, was enhanced approximately twice. The energy transfers from 2F5/2 (the first excited state) → 2F7/2 (the grand excited state) of Yb3+ to 4I11/2 (the second excited state) → 4I15/2 (the grand excited state) and 4I15/2 → (the first excited state) 4I15/2 of Er3+ was observed.

Coincidence gamma-ray angular correlations of the cascade decays from the 3.34- and 4.47-Mev states in Ne22 through the first excited state have been measured. The levels were excited by the reaction F19 (α, p)Ne22. The correlations give an unambiguous spin assignment of 4 to the 3.34-Mev state; the analysis of the correlations from the 4.47-Mev state is not unique, allowing spin 2 or 3. The quadrupole-to-dipole amplitude ratio for the primary radiation is −0.11 ± 0.03 or −1.07 ± 0.10, respectively, for the spin-2 and spin-3 assignments.

Integral rotation of the 3/2+ 320-keV level of 45Ti and the 7/2− 160 keV level of 47Ti recoil implanted in iron and nickel were measured following (α,n) reactions in 42Ca and 44Ca on magnetized backings. The average hyperfine field at 45Ti nuclei is Hhf(TiFe) = −45 ± 10 kOe and Hhf(TiNi) = −15 ± 3kOe. The g factor of the 7/2− first excited state of 47Ti is −0.55 ± 0.17.

The nuclear quadrupole interaction of 187W(β-)187Re in W(VI)-EDTA complexes at room temperature was determined by time differential perturbed angular correlations (TDPAC) to be VQ = 1270(8) MHz with an asymmetry parameter η= 0.403(4). While the coordination geometry of the Mo(VI)- EDTA complex is known, there appears to be none for the W-analogue. The rather similar asymmetry parameters for the 187W(β-)187Re in W(VI)-EDTA complex and for the 99Mo(β-)99Tc in Mo(VI)- EDTA complex, determined previously, supports the idea that the coordination geometries in the Moand W-complexes are similar
