“…It is important to remember that, in the A = 31 isobars, the results of the analysis will be rendered uncertain since we do not have information on the relevant B(E1) value in 31 Si. In the A = 35 isobars, on the other hand, we do not have an experimental matrix element for the T = 1/2 → T = 1/2 component in 35 Ar, for which we have been forced to rely on scaling from a predicted B(M2) value [18]. Figure 4 illustrates the allowed values of the isospin mixing angles φ i and φ f in the A = 31 nuclei.…”

We investigate whether isospin mixing can be determined in a model-independent way from the relative strength of E1 transitions in mirror nuclei. The specific examples considered are the A = 31 and A = 35 mirror pairs, where a serious discrepancy between the strengths of 7/2 − → 5/2 + transitions in the respective mirror nuclei has been observed. A theoretical analysis of the problem suggests that it ought to be possible to disentangle the isospin mixing in the initial and final states given sufficient information on experimental matrix elements. With this in mind, we have obtained a lifetime for the relevant 7/2 − state in 31 S using the Doppler-shift attenuation method (DSAM). We have then collated the available information on matrix elements in order to examine the level of isospin mixing for both A = 31 and A = 35 mirror pairs.

“…Under physiological conditions, extensive cell to cell contact would not be needed as the dense innervation would be capable of producing fast synchronous activity. This tissue has been described as demonstrating multiunit behaviour (Prosser 1962;Jewel1 1968) observed experimentally in double compartment bath experiments by Goto et a1 (1976). Vasa deferentia were incubated in a bath divided into two sealed compartments and addition of agonist toone compartment produced only partial contraction, indicating poor electrical coupling of smooth muscle cells.…”

On the importance of agonist concentration-gradients within isolated tissues. Increased maximal responses of rat vasa deferentia to (–)-noradrenaline after blockade of neuronal uptake

It is assumed often that blockade of agonist uptake processes in isolated tissues results only in shifts to the left of the concentration‐response curves to the agonist with no concomitant increase in the maximal response. This may not be true in tissues where diffusion is not fast enough to permit penetration of the agonist to a sufficient number of muscle cells for production of tissue maximal response. Under these circumstances an agonist‐concentration gradient is created within the tissue which, when altered, could lead to an increase in the maximal response to the agonist. The increased maximal responses of rat vasa deferentia to (–)‐noradrenaline after blockade of neuronal uptake by either cocaine or desmethylimi‐pramine have been analysed in terms of a concentration‐gradient hypothesis. The data are compared with a theoretical calculation based on a model of restricted diffusion of enzymesubstrates into structured tissues. Both the experimental data and theoretical calculations suggest that an altered concentration‐gradient of (–)‐noradrenaline within the muscle layers of rat vasa deferentia is responsible for the increased maximal response. The effects of such gradients are discussed in terms of quantitation of drug‐receptor phenomena and as a caveat to ascribing increases in maximal responses to post‐synaptic effects of uptake inhibitors.

“…Several studies through the 34S(p, y)35C1 reaction had been made prior to 1972, when the present investigation was initiated: 48 (p, ~) resonances in the energy range Ep=700-2700 keV were observed by Antufev eta[. [1], Dubois [2] and Oleksiuk and Prentice [3], Hazewindus et al [4] studied 9 resonances with a NaI-detector; later, with Ge(Li)-detectors, the decays of 4 resonances were studied by Watson et al [5], Wiesehahn [6] and Prosser and Harris [7]. The spins and parities for excited states up to 4 MeV are rather well known from recent 34S(3He, d) experiments [8,9] and 32S (c~, p y) 35 C1 experiments [10].…”

Fortyeight resonances of the 34S(p, y)aSCl reaction in the proton range Ep= 1 --2 MeV have been observed. Gamma decay of twentyeight of these was investigated by means of a 55 em 3 Ge(Li) detector, and the energies and branching ratios of several bound states have been determined. The Q-value was found to be 6367.0_ 1.5keV. The lifetimes 150__20, 400__+140, 19-t-4, 14-t-2, 145+50, 20+5, 20+4, 42+4 and 7-1-3 fs were determined with the DSA method for the states at 1219, 1763, 2694, 3003, 3944, 3967, 4059, 4178 and 4882 keV, respectively. The experimental transition strengths were found to be in agreement with those given by manyparticle shell-modell calculations.
