Apparatus design and procedures are described for the determination of the vapor pressures of naturally occurring neon (nWe) and the pure isotopes and *,Ne from their triple points (TP) to their normal boiling points (NBP). The data have been fitted to vapor-pressure equations with rootmean-square deviations of * 2.5 to * 4.7 N/ma ( & 0.019 to rt 0.035 mmHg). The TP pressures (P) and the TP and NBP temperatures (T) were found to be: TP NBP P T, K T, K (325.02 i 0.10 mmHg) (324.97 i 0.10 mmHg) n*tNe 43 332 f 13 N/m2 24.553 & 0.001 27.096 &0.001 20Ne 43 326 i 13 N/m2 24.540 i 0.001 27.084 i 0.001 W e 43654 & 13 N/m2 24.687 i 0.001 27.211 i 0.001 (327.43 i 0.10 mmHg (The temperatures are in terms of the NBS-1955 provisional temperature scale. The figures after the & symbol indicate estimated uncertainties). The calculated vapor pressures of the isotopic nWe, based on Raoult's law of solution and the 4 Metrologia observed vapor pressures of the pure isotopes, are in agreement within the combined precision of the measurements with the observed values of nWe.14 G.

“…Table 1 gives the set of 41 cells and seven gases involved in the studies. The following references should be consulted for information about cell fabrication and performances: ASMW [ l l ] , BIPM [12], IMGC 161, NBS [17][18], NIM [19], NRLM [20]. Cell ageing after sealing ranged from a few months (at the beginning of the circulation) to more than 8 years (at the end).…”

An International Intercomparison of Fixed Points by Means of Sealed Cells in the Range 13.81 K–90.686 K

An International Intercomparison of Fixed Points by Means of Sealed Cells has been conducted under the auspices of the Comité Consultatif de Thermométrie (CCT) between 1978 and 1984. Forty-one sealed cells, realizing the triple point of seven different substances, defining both primary fixed points of the IPTS-68 and secondary fixed points in the temperature range from 14 K to 90 K, were supplied by nine laboratories. They were measured in eleven national laboratories around the world, against the fixed points realized in these laboratories (both in open cryostats or in other sealed cells). Some 150 independent series of data were produced, from almost 300 melting experiments, representing some 2,300 equilibrium temperature values. The basic sets of results are presented, concerning the agreement between different cell realizations and the comparison of national IPTS-68 realizations. Data connecting the results of this intercomparison with that performed at NPL in 1975 using calibrated thermometers are also given.

“…An axial zero-field splitting leads to a splitting of the S = 10 state into 21 levels, each characterized by a spin projection quantum number, m s , where −S m s S. The integration of these magnetic molecules into magnetic storage devices requires the successful production of thin films of the material. Recently, films have been made using various techniques and characterized by different devices [17][18][19][20][21][22][23]. If one wants to use the film in a device, a problem may arise: the film may be good immediately after growth but may deteriorate with time.…”

Electric transport properties of Mn₁₂-acetate films measured with self-assembling tunnelling junction

Electric transport properties of Mn12-acetate films have been measured with a self-assembling tunnelling junction device at a liquid helium temperature of 4.2 K. For fresh films, clean I–V characteristics including the zero bias feature and the stair-case like I–V curves are observed. For stored films, however, all those features disappear and ‘telegraph’ noise appears, which indicate the deterioration of the Mn12-acetate molecules.
