Time-differential angular-correlation measurements on the 1408–122 keV cascade of 152Sm were performed in liquid EuCl3 and Eu(NO3)3 sources at a time resolution of 450 ps. The results obtained are λ2 = (8.3 ± 2.0) × 107 s−1, A2(0) = 0.218 ± 0.008 in SmCl3 and λ2 = (2.5 ± 2.1) × 107 s−1, A2(0) = 0.206 ± 0.018 in Sm(NO3)3. Integral angular-correlation measurements on the 244–122, 964–122, and 1112–122 keV cascades were also performed in the same chloride and nitrate sources using a NaI(Tl)–HPGe system. Using the values of λ2, the unperturbed angular-correlation coefficients for these cascades are determined and therefrom the mixing ratio of the λ transitions are found to be δ(1408) = 0.05 ± 0.01, [Formula: see text] and [Formula: see text]. The magnetic moment of the 122 keV 2+ level was remeasured and a value of μ = 0.80 ± 0.06 nm was obtained.

Small Rotation

Perturbed angular correlation measurements have been made on the decay of 181Hf implanted in iron. The average integral rotation angle for the 136 keV 9/2+ state of 181Ta is ωτ = 0.051 ± 0.004 rad. For the internal field on Ta in iron of 640 kOe, this gives a nuclear g factor of 0.27 ± 0.04. Alternative explanations of the small rotation are discussed. The E2/M1 mixing ratio of the 136 keV transition was found to be δ = −0.44 ± 0.04.

AbstractBilayers of Cu/Fe and Cu/V and multilayers of Ni/Fe have been grown under high vacuum and ultra high vacuum conditions respectively with [111] epitaxy. Multilayer layer thicknesses ranged from 3 monolayers to 15 monolayers per layer. Improved epitaxy of the UHV growth was, we believe, due to the better vacuum although perfect material could only be obtained for growth within a narrow and shifting substrate temperature ‘window’. Possible shortfall in the quality of the Cu backing layer epitaxy was averted by a 2hr anneal at 425°C.In the Fe/Ni multilayers the Fe was observed to adopt the FCC lattice rather than the equilibrium BCC lattice for layer thicknesses less than 10 monolayers. This change of structure coincided with a reduction in sample magnetic moment per volume attributed to a collapse of the Fe moment to a value 7 times less than bulk.

With the help of the automated system for the classification of carcasses of pigs, AutoFOM ultrasound have been processed 56682 carcasses of slaughter pigs with an average carcass weight of 94.3 kg. The mass and yield of muscle tissue from the main cuts in the carcass is shown. Correlation coefficients between the mass and the content of muscle tissue in the carcass and the main (premium) cuts (ham, neck, shoulder, belly, and loin) were studied. It is shown how the increase in the weight of each of the cuts affects the content of muscle tissue in the carcass and in the cut. For example, it was found that when the weight of the belly is increased by 10 kg (from 6 to 16 kg), the percentage of muscle tissue from carcass is reduced by 3.3% (from 54.5 to 51.8%), which is approximately 0.33% for 1 kg of additional weight of the belly. With an increase in the weight of the loin from 4 to 14 kg, the yield of muscle tissue from the carcass on the contrary increased by 11.6%, i.е. 1.16% for each additional kg of loin weight. A value (in absolute and relative units) of the main cuts is given. The conclusion is made about the prospects of using the obtained data in the creation of a specialized terminal line of pigs, characterized by an increased content of weight of premium cuts in the carcass.ContributionAll authors bear responsibility for the work and presented data.
