We report a time-resolved investigation of the low-lying state, B-2 Sigma, of gaseous SrF using laser spectroscopy with the following derived zero-pressure lifetime tau(B (2) Sigma(v' = 0)) = 25.4 +/- 0.8 ns. Such measurements constitute an important contribution to our overall understanding of excited alkaline earth halides. They are also applied to the interpretation of molecular dynamic investigations of halogen atomic abstraction reactions by excited atoms, in the present case, Sr[5s5p(P-3(J))], with molecules such as CH3F where the A --> X and B --> X chemiluminescence emissions are employed in the time-domain to monitor the production of electronically excited SrF on collision.

Frequency response function measurement and parametric SISO system modelling of a gyro-stabilized infrared electro optic gimbal system Ozdogan, Gokhan; Leblebicioğlu, Mehmet Kemal (2016-05-01) In this research study, a single axis (inner azimuth gimbal) of a four-axis gyro-stabilized electro optic gimbal system is modelled through experimental investigation in the frequency domain, and the results of this investigation are presented. The dynamic behaviour of the mechanical system is obtained from input and output signals, strictly speaking, nonparametric measurements. Detecting and measuring the nonlinear distortions allows a better understanding and gives an intuitive insight into the error sour...
Energy calibration and resolution of the CMS electromagnetic calorimeter in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (IOP Publishing, 2013-09-01) The energy calibration and resolution of the electromagnetic calorimeter (ECAL) of the CMS detector have been determined using proton-proton collision data from LHC operation in 2010 and 2011 at a centre-of-mass energy of root s = 7 TeV with integrated luminosities of about 5 fb(-1). Crucial aspects of detector operation, such as the environmental stability, alignment, and synchronozation, are presented. The in-situ calibration procedures are discussed in detail and include the maintenance of the calibratio...
Measurement of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) cross sections in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (2013-11-01) The Upsilon(1S), Upsilon(2S), and Upsilon(3S) production cross sections are measured using a data sample corresponding to an integrated luminosity of 35.8 +/- 1.4 pb(-1) of proton-proton collisions at root s = 7 TeV, collected with the CMS detector at the LHC. The Upsilon resonances are identified through their decays to dimuons. Integrated over the Upsilon transverse momentum range p(T)(Upsilon) < 50 GeV/c and rapidity range vertical bar y(Upsilon)vertical bar < 2.4, and assuming unpolarized Upsilon produc...
Pulse phase resolved x-ray spectroscopy of four accretion powered millisecond pulsars Çolak, Sıdıka Merve; Baykal, Altan; Department of Physics (2014) In this thesis, pulse phase resolved X-ray spectroscopy of four accretion powered millisecond pulsars which are IGR J00291+5934 , IGR J17498-2921 , XTE J0929-314 and XTE J1807-294 will be presented. Phase dependent changes during their outbursts will be checked for possible correlations of spectral parameters such as photon index and blackbody temperature with rotation phase using archive of Rossi X-ray Timing Explorer (RXTE) observations. In the analysis of IGR J17498-2921 in 2011 outburst , positive corre...
Pseudorapidity dependence of long-range two-particle correlations in pPb collisions at root sNN=5.02 TeV Khachatryan, V.; et. al. (2017-07-01) Two-particle correlations in pPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV are studied as a function of the pseudorapidity separation (Delta eta) of the particle pair at small relative azimuthal angle (|Delta phi| < pi/3). The correlations are decomposed into a jet component that dominates the short-range correlations (|Delta eta| < 1), and a component that persists at large Delta eta and may originate from collective behavior of the produced system. The events are classified in term...
