“…For completeness purposes we discuss the possibility for field ionization of electrons from Rydberg states of the projectile ion, as this has been an issue for electrostatic zero-degree electron spectrometers [31,32]. We consider that the magnetic field of the first spectrometer dipole magnet may lead to field ionization of U 88+ (1s 2 2snl ) projectile ions, that have captured a target electron into a highly excited nl state, as discussed in Ref.…”

For U 89+ projectiles colliding at a beam energy of 75.91 MeV/u with a N 2 target, we present a coincidence measurement between the cusp electrons emitted under an angle of 0 • with respect to the projectile beam and the photons emitted under a polar angle of 90 • . This radiative-electron-capture-to-continuum cusp directly probes the theory of electron-nucleus bremsstrahlung up to the high-energy endpoint in inverse kinematics. In the present study, significant improvement with respect to the experimental accuracy has been achieved, resulting in a finer agreement between experimental and theoretical results.

“…Stark beat studies for hydrogen [13][14][15], alkali metal [16][17][18] and highly charged carbon [19] were performed with beam foil excitation. The atom polarizabilities [20,21] and molecule electronic dipole moments [22][23][24][25][26] have been investigated by analysis of electric field dependence of the beat frequency using pulsed laser excitation.…”

The Stark Quantum Beat of Ne Fluorescence in the Vacuum Ultra Violet Region

et al. 2003

The Stark quantum beats between the M ¼ 0 and M j j ¼ 1 magnetic sublevels of Ne atom Rydberg states were observed in electric fields up to 5 kV/cm, using synchrotron vacuum ultra violet radiation. It was confirmed that the beat frequencies depend on the electric field strength squared. The angular correlation of the fluorescence intensities and the Stark beat amplitudes of some Rydberg states were measured and the experimental results agree with the theoretical predictions. The tensor polarizabilities of the 26 Ne Rydberg states were determined from the field dependence of the M ¼ 0 and M j j ¼ 1 splitting. A comparison between the experimental frequencies and the values calculated using the jl coupling scheme and the MQDT analysis was attempted.Ã

“…5). But historically, hemolysin producers were extremely rare in near shore 287 areas of the Atlantic US coast (25) and represented only about ~1% of isolates in an estuary of 288 NH as of a decade ago (27) limiting the potential for interacting partners or sources for acquired 289 VPaI. Given this historical context, it is remarkable that two different clades from the same 290 lineage independently acquired different VPaI-which for clade II ST631 occurred prior to 2007 -291 well before the recent shift in abundance of hemolysin producers.…”
