A comparison is presented for the ground state of the helium atom of high order Rayleigh-Schri)dinger perturbation theories based upon a hydrogenic. a screened hydrogenic, a Hartree and a modified Hartree local zero-order hamiltonian. The hydrogenic zero-order schemes are superior tc the Hartree zer
Experiments on helium with a large diameter (1 m) rotating cryostat at speeds up to 50 Hz are described. Radial temperature distributions have been measured with axial pressures ranging from 25 x 103 to 2.0 x 10 s Nm -2. It is concluded that the temperature distributions are isentropic to within 30
Fibre-reinforced-plastic (FRP) cryostats have been developed for various cryogenic fields, such as superconducting magnets and cryogenic electronics. The FRP cryostats ought to be used as liquid-helium containers for the operation of a.c. and/or pulse superconducting magnets because the eddy-current
In this Paper, the thermodynamic properties of nitrogen such as enthalpy and entropy calculated from the BWR equation of state 1 using eight coefficients, which were optimized previously 2 are presented. The thermodynamic properties calculated are found to be satisfactory in the region from atmosphe
