Observation of a shape resonance in the a 3 ( u 1 state of 7

چکیده
Using the most accurate potential curves available for the a (u 1 and X (g 1 states of lithium molecules, we compute the positions of shape resonances. We also calculate the deexcitation probability from a bound level v8 with rotational number N8 to the continuum of the lower state, and conclude that a shape resonance should be measurable for the transition 2 )g ̃a (u 1 . Such a shape resonance has been identified from the spectra of the transition from the v852,N854 level of 2 )g into the N954 continuum of a (u 1 . Its position is in good agreement with the theoretical prediction. @S1050-2947~99!09909-6#

Resting-state Functional Connectivity During Controlled Respiratory Cycles Using Functional Magnetic Resonance Imaging
Introduction: This study aimed to assess the effect of controlled mouth breathing during the resting state using functional magnetic resonance imaging (fMRI). Methods: Eleven subjects participated in this experiment in which the controlled “Nose” and “Mouth” breathings of 6 s respiratory cycle were performed with a visual cue at 3T MRI. Voxel-wise seed-to-voxel maps and whole-brain region of i...
متن کاملAnalyzing the Optical Properties and Peak Behavior Due to Plasmon Resonance of Silver Cubic-Shape Nanostructures by Means of Discrete Dipole Approximation
In this article, the optical properties of silver cubic-shape nanostructures (SCNs) were analyzed by employing the discrete dipole approximation (DDA) in aqueous media. The absorption, dispersion and extinction cross-sections of these nanostructures were calculated based on the wavelength change of the incident light in the visible and near infrared region. Moreover, the height change, waveleng...
