Jubilees of radio-frequency spectroscopy
Notes and Records of the Royal Society of London, 1997The years 1994–96 are marked by a series of golden jubilees: the first electron magnetic resonance experiment at Kazan (Zavoisky, 1945); nuclear magnetic resonance at Harvard (1945) and nuclear magnetic induction at Stanford (1945); ferromagnetic resonance in Oxford (1946); and microwave spectroscopy of gases (Oxford, and at several laboratories in the

Radio-Frequency Spectroscopy: Broad Introduction
2011Radio-frequency (RF) spectroscopy has emerged as a powerful probe of cold atoms. It provided the first evidence of BEC in dilute hydrogen gases, probed the pair structure and binding energy across the BEC/BCS crossover, and was used to study the quantum phase transition between Mott and superfluid states of lattice boson.

Radio-Frequency Spectroscopy: Outreach
2018This chapter gives a short review of the spectroscopic techniques that are specific to Penning traps, since they make dedicated use of the confining fields and their controllable properties. In particular, we show how precise measurements of the oscillation frequencies of particles in the radio-frequency domain may be used to infer spectroscopic ...

Spectroscopy. Volume I—Atomic, Microwave and Radio–Frequency Spectroscopy
Physics Bulletin, 1962By S. Walker and H. Straw London: Chapman and Hall Ltd. Pp. xix + 267. Price 50s. This volume is the first of two books which are attempting to cover the application of spectroscopy in the chemical field where the determination of molecular structure has been helped considerably by use of modern spectroscopic techniques.

Multi-Object Spectroscopy and Radio Surveys
1997Studies of radio-source astrophysics and cosmology are based on samples for which typically 10 to 100 redshifts have been measured. Such samples are grossly inadequate given the diversity of radio-source populations and range of luminosities present. Redshift-acquisition has been long and tortuous; there are ≤ 103 known for a totality of ∼ 105 radio ...

Radio spectroscopy of the solar corona
Modern astronomy: from the Early Universe to exoplanets and black holesThe presence of continuous cooling and heating processes is a crucial condition that determines the existence of the solar corona. The defining aspects of the corona include the magnetic field, low plasma density, and high temperature of the corona. In this regard, the study of low-contrast structures in optical ranges is limited even with the use of ...

Radio-frequency spectroscopy of excited atoms
Reports on Progress in Physics, 1959Radio-frequency and optical spectroscopy are compared. Standard results in the theory of hyperfine structure are quoted. The excitation of atoms and the detection of radio-frequency resonances are discussed quantitatively. Experiments are described in which the techniques of `double resonance', electron impact, and atomic beams are used.

3D Spectroscopy in Distant Radio Galaxies
EAS Publications Series, 2001Star formation rates in distant radio galaxies are crucial for understanding the evolution of galaxies. Most processes at works in these targets observed at the most remote epochs are directly or not related to primeval sources of star formation: interplays of starbursts and AGNs, interactions of radio jets with environmental clouds.

Collision Broadening and Radio-frequency Spectroscopy
1996Spectroscopy naturally began at optical wavelengths, then spread to the ultraviolet and infrared. Gas discharge tubes at low pressures reduced collision broadening; narrow lines and interferometric techniques made possible high-resolution spectrometry, including hyperfine structure.
