ATOMIC PHYSICS four extends the sequence of books containing the invited papers awarded at every one "International convention on Atomic Physics." FICAP, the fourth convention of this sort considering that its foun­ dation in 1968, was once held on the college of Heidelberg. The objective of those meetings, to hide the sector of atomic physics with all its varied branches, to study the current prestige of study, to restore the basic foundation of atomic physics and to stress destiny advancements of this box in addition to its functions was once met via greater than thirty invited audio system, leaders within the box of atomic physics. Their talks have been supplemented through greater than 2 hundred contributed papers inside the FICAP booklet of Abstracts. This quantity starts with papers given in honour and reminiscence of E. U. Condon, to whom this convention used to be committed. It maintains with articles on basic interactions in atoms and Quantum electrodynamics, at the quickly progressing box of excessive power heavy ion collisions and Quasi-molecules, on digital and atomic collisions and the constitution of digital and ~-mesic atoms. the quantity closes with contributions in regards to the software of l. a.­ sers in atomic physics, a brand new box of drastically expanding value to basic experiments in addition to purposes. We think that this booklet incorporates a very stimulating account of the current major streams of analysis in atomic physics and its attainable destiny di­ rections.

Whilst I encountered the belief of chaotic habit in deterministic dynami­ cal structures, it gave me either nice pause and nice reduction. The foundation of the nice reduction was once paintings I had performed past on renormalization crew houses of homogeneous, isotropic fluid turbulence. on the time I labored on that, it was once popular to ascribe the it sounds as if stochastic nature of turbulent flows to a couple form of stochastic using of the fluid at huge scales.

2) becomes increasingly important, though this happens gradually and at larger and larger values of R for increasing values of v. Figure 4 shows a reI ie f map of th is term on the (0,9 12 ) coord i nates; note how narrow is the base of the positive energy spike, which represents the electronelectron repulsion, and how the nuclear attraction tends to draw the system into the ditch along 0=0 (or in its mirror image at 0=~1T). Equation (2) is transformed into a system of coupled ordinary equations by expanding ~ at each value of R into a complete system of functions of the five angular variables, cl> (R;D).

However, the noise leads to serve difficulties in the solution of this type of "reserved" problems as has been described somewhat in 21 • A useful new way to attack these problems is offered by the method of "magnetic scanning" recently developed in our laboratory: The light absoption of vapours in a magnetic field is measured 22 . In this way a component of the absorption line of 8 7 Rb can be made coincident with a hyperfine component of the 85Rb emission line 24 • From the size of the magnetic field the line shifts in the presence of various buffer gases (He,Ne,Ar,Kr,N2) have been determined.

2. The process leading to this state must be anisotropic, or the original state must have had an alignment. In the gas discharge in the main three processes can produce excited atoms:collisions between the par~ ticles, absorption of light, and the decay of higher excited states. All three processes can give rise to aligned atomic states, but we ,as well as the authors of a later independent paper 2 ;believe that alignment is mainly due to the generation of excited states by absorption of light.
