TL;DR: In this article, the decay of the 3.2 s (1+) and 44 s (4, 5+)120In isomers and the 15.8 d (8−)120Sb isomers have been investigated using Ge(Li) spectrometers and prompt and delayed Ge (Li)-NaI(Tl) coincidence techniques.
Abstract: Gamma rays in the decay of the 3.2 s (1+) and 44 s (4, 5+)120In isomers and the 15.9 min (1+) and 5.8 d (8−)120Sb isomers have been investigated using Ge(Li) spectrometers and prompt and delayed Ge(Li)-NaI(Tl) coincidence techniques. The constructed level scheme of120Sn contains 18 levels at the following energies (keV): 0 (0+), 1171.6 (2+), 1875.6 (0+), 2096.9 (1, 2, 3), 2160.7 (0+), 2195.0 (4+), 2284.8 (5−), 2355.6 (2+), 2421.2 (1, 2, 3), 2466.3 (4+), 2482.1 (7−), 2643.5 (4+), 3058.6 (4+), 3179.7 (4+), 3349.9 (3, 4+), 3440 (3, 4+), 3447.6 (5, 6+) and 3777 (4+). The levels are compared with the levels obtained from recent charged-particle reaction studies and the structure of120Sn is briefly discussed in view of the latest quasiparticle calculations.

TL;DR: In this article, the correlation functions of 10 γ-ray cascades in 200Hg have been measured using a200Tl source and a Ge(Li)-NaI(Tl) coincidence spectrometer arrangement.
Abstract: Directional correlation functions of 10 γ-ray cascades in200Hg have been measured using a200Tl source and a Ge(Li)-NaI(Tl) coincidence spectrometer arrangement. Values of the mixing parameter δ for several transitions are determined, and the spin assignments for the following levels in200Hg are established (level energies are given in keV): 1029.4 (0+), 1254.2 (2+), 1573.7 (2+), 1593.4 (2+), 1641.5 (2+), 1730.9 (2+) and 1775.6 (3+).

TL;DR: In this article, a detailed study of γ-rays and γray cascades from 26.1 h 200 Tl has been carried out employing Ge(Li) detectors, an anti-Compton spectrometer and a Ge (Li)-NaI(Tl) coincidence spectrometers.

TL;DR: Propranolol increased the concentration of palmitic and C 18 -unsaturated fatty acids in the plasma of the titmouse and Noradrenaline increased the hepatic glycogen content.
Abstract: 1. 1. Propranolol increased the concentration of palmitic and C 18 -unsaturated fatty acids in the plasma of the titmouse. 2. 2. Noradrenaline did not affect the contents of any free fatty acids studied. It also increased the hepatic glycogen content.

TL;DR: For example, this paper found that 4-, 6-, 8-, and 10-yr-old children learned nonsense phonological sequences that varied in grammaticality by violating 0, 1, or 2 phonological rules of their native language.
Abstract: 4 groups of 15 4-, 6-, 8-, and 10-yr.-old children learned nonsense phonological sequences that varied in grammaticality by violating 0, 1, or 2 phonological rules of Ss' native language. The youngest age group made fewer errors in learning the most nongrammatical phonological sequences than in learning grammatical ones. With the 10- and 8-yr.-olds an opposite trend was found. The differences were not statistically significant. Implications for second language learning were discussed.

TL;DR: In this paper, a simple fast coincidence method which allows simultaneous recording of coincidence and random coincidence spectra is described, based on the properties of a standard two-parameter pulse-height analyzer system and no special electronics is required.
