In this study we introduce the spectroscopic modifications of Pippard relations and apply them to the disorder-induced Raman modes of NH4Cl in the first-order (P = 0) and second-order (2.8 kbar) phase regions in this crystalline system. We obtain Linear variations of the specific heat C-p with out observed frequency shifts [(l/nu)(partial derivative nu/partial derivativeT)(p)] of those Raman modes studied for the first-order and second-order phase transitions in NH4Cl. This will be discussed in detail.

Ultrasonic frequency shifts close to the first order and tricritical phase transitions in NH4Cl
Yurtseven, Hasan Hamit; Bas, M (2001-12-01)
This study examines our spectroscopic modifications of the Pippard relations using the ultrasonic frequencies of the q[110] and q[1 (1) over bar0] modes for the first order phase transition in NH4Cl. We also examine our relations using the ultrasonic frequencies of the q[110] mode for the tricritical phase transition in this crystal. From our plots of the specific heat C-p as a function of the frequency shifts (1/nu)(partial derivative nu/partial derivativeT)(p), we obtain that our spectroscopically modifie...
Ultrasonic frequencies calculated for the q[100] mode in the first-order, tricritical and the second-order phase transitions of NH4Cl
Yurtseven, Hasan Hamit (2001-06-01)
This study correlates the volume changes to the ultrasonic frequencies of the q[100] mode of NH4Cl for the first-order, tricritical and the second-order phase transitions in this crystal. Using these correlations we were able to calculate the ultrasonic frequencies of this mode at the pressures of 0, 0.6 and 1.1 kbar (first-order), 1.6 kbar (tricritical) and 2.15 kbar (second-order) by means of the volume change data from the literature. Our calculated frequencies are in good agreement with the observed dat...
Critical behaviour of the Raman frequency shifts in the vicinity of the lambda-phase transition in NH4Br
Yurtseven, Hasan Hamit (2006-01-01)
This study gives the temperature dependence of the Raman frequencies for the lattice mode of upsilon(7) (TA) and the internal mode of upsilon(2) close to the X-phase transition (T-lambda=234K, P=\) in NB4Br.
Spectroscopic modifications of the Pippard relations for NaNO2 in the sinusoidal antiferroelectric phase
Tari, O; Yurtseven, Hasan Hamit (2002-06-01)
We establish in this study a linear variation of the specific heat C-p with the frequency shifts (1/nu)(partial derivativenu/partial derivativeT) in the sinusoidal antiferroelectric phase of NaNO2, according to the first Pippard relation which we have modified spectroscopically. For this linear relationship we use the Brillouin frequencies of acoustic phonon modes for the q[010], q[001] and q[100] modes of NaNO2 in the sinusoidal antiferroelectric phase. We then calculate dT/dP values due to those modes stu...
Angular analysis of the decay B+ -> K+mu(+)mu(-) in proton-proton collisions at root s=8 TeV
Sirunyan, A. M.; et. al. (American Physical Society (APS), 2018-12-01)
The angular distribution of the flavor-changing neutral current decay B+ -> K+mu(+)mu(-) is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5 fb(-1). The forward-backward asymmetry A(FB) of the dimuon system and the contribution F-H from the pseudoscalar, scalar, and tensor amplitudes to the decay width are measured as a function of the dimuon mass squared. The m...
