We report on high-resolution spectroscopy with two different samples of calcium atoms, in a laser-cooled and deflected beam and in a magneto-optical trap. The atomic beam was excited by spatially separated laser fields. For spectroscopy with stored a

Separated field excitation of a calcium atomic beam using four traveling laser fields represents two distinct atom interferometers utilizing the internal degrees of freedom of the atoms. Phase shifts between the atomic partial waves have been realize

Physics and experimental results of atom interferometry are reviewed and several realizations of atom interferometers are summarized. As a typical example of an atom interferometer utilizing the internal degrees of freedom of the atom, we discuss the

We report on high-resolution spectroscopy with dye and diode lasers and with three different samples of Ca atoms, in an effusive beam, in a laser cooled beam, and in a magneto-optical trap. The results should allow to improve the Ca, optical frequenc

An optical frequency standard based on a dye laser stabilized to the Lamb dip of the Doppler-broadened Ca intercombination line is reported. The measured depth of the Lamb dip depends strongly on the laser power and the excitation geometry and can be

Ein Kalziumatomstrahl, der nacheinander durch vier koharente Laserwellenfelder lauft, zeigt bei der Drehung der Atomstrahlapparatur eine Frequenzverschiebung seines Absorptionsspektrums. Diese von der Rotationsgeschwindigkeit abhangige Frequenzversch

A calcium atomic beam excited in an optical Ramsey geometry was rotated about an axis perpendicular to the plane defined by the laser beams and the atomic beam. A frequency shift of the Ramsey fringes of several kHz has been measured which is proport

The thermal velocity distribution of a calcium atomic beam was compressed into a narrow velocity distribution with selectable velocities. Subsequently these slow atoms were deflected by an angle of 30° by a one-dimensional optical molasses. In the d

IN molecular liquids that may form dimers, for example by hydrogen-bonding, direct evaporation of dimers is possible when these form stable molecules. A gradual change from monomer to dimer evaporation would be expected at pairwise molecular bond ene
