Ionization potentials of CaF and BaF
The Journal of Chemical Physics, 1994Although the alkaline earth–monohalide compounds, MX, have been extensively studied, their ionization potentials to MX+ are only known to within a few tenths of an eV. Using an improved electron impact ionization potential measurement to assist in arranging spectroscopic vibronic band origins into Rydberg series, we report high precision ionization ...

Architecture of human BAF complex
Science, 2020Structural Biology The SWI/SNF family chromatin remodelers regulate chromatin and transcription. The protein complexes BAF and PBAF are mammalian SWI/SNF remodelers that play essential functions in diverse developmental and physiological processes. He et al.

Simulations of Positron Capture at Ce+BAF
IPAC'24, NASHVILLE, TN, May 19, 2024We present an initial capture concept for the continuous wave (CW) polarized positron beam at the Continuous Electron Beam Accelerator Facility (CEBAF) upgrade at Jefferson Lab. This two-step concept is based on (1) the generation of bremsstrahlung radiation by a longitudinally polarized electron beam (1 mA, 120 MeV, >90% polarization), passing through

Analysis of Microbial Characteristics for BAF
Applied Mechanics and Materials, 2013In the biological aerated filter, the number of microorganisms and activity play a key role on the removal of the organic matter. Studying the microbial mass distribution is a useful method for understanding the organic matter degradation mechanism, and it can provide theoretical basis for the operations.

A BAF-centred view of the immune system
Nature Reviews Immunology, 2004Chromatin structure dictates whether DNA templates are accessible to nuclear proteins; therefore, it is tightly regulated. To reconfigure chromatin, cells often mobilize 'chromatin-remodelling complexes' that use energy to disrupt histone-DNA contacts.

SPIE Proceedings, 1998
This paper introduces the properties of BaF 2 crystal material. According to these properties material selecting is discussed including initial separation and finish separation, e.g. checking crystal lithogenesis, intercalation, cloud, uniformity and stress and so on. Determine methods are given also.

Spectroscopy Letters, 1972
Abstract The emission spectrum of the Green Band System of BaF has been photographed on a 35-feet concave grating spectrograph in the second order. Some new bands have been observed and analysed. Precise measurements of the Q1 band-heads are used to calculate the band-origins which have led to the determination of accurate molecular constants for the ...

The metastable A′ 2Δ state of BaF
Chemical Physics Letters, 1988Abstract Absorption of Ar + laser lines in the C 2 Π-X 2 Σ + system of BaF leads to infrared fluorescence, C 2 Π-A′ 2 Δ. This has been recorded at high resolution by Fourier-transform spectrometry. Constants for the 2 Δ state have been determined, and some improvements in the values of the constants for X 2 Σ + , B 2 Σ + and C 2 Π are also ...
