Self-induced transparency in acoustic paramagnetic resonance

NS Shiren - Physical Review B, 1970 - APS
… (17)], an analytic form may also be deduced without the restriction n, = 0, … If Tz were
dominated by spinspin interactions then the values for n( S,) = 2 transitions should theoretically be …

Electron-Nuclear Double-Resonance Determination of the and Hyperfine Tensors for Polyacetylene

H Thomann, LR Dalton, Y Tomkiewicz, NS Shiren… - Physical review …, 1983 - APS
… suggested that the linewidth of both protonated and deuterated cps-polyacetylene could
be accounted for by assuming the hyperfine coupling at site n to be a„=(ao/N) sech'(n/X) cos'((m/…

Application of the area theorem to phonon echoes

EL Hahn, NS Shiren, SL McCall - Physics Letters A, 1971 - Elsevier
… various concentrations, N, of Cr 3… N 2, for N < 0.3% by weight. However, for larger
concentrations the measured intensity deviates from the N 2 dependence, reaching a peak value at …

GEM-NI A System for Creating and Managing Alternatives In Generative Design

…, R Woodbury, M Elkhaldi, N Shireen… - Proceedings of the 33rd …, 2015 - dl.acm.org
We present GEM-NI -- a graph-based generative-design tool that supports parallel exploration
of alternative designs. Producing alternatives is a key feature of creative work, yet it is not …

Some effects of group-velocity dispersion on parametric interactions

J Armstrong, S Jha, N Shiren - IEEE Journal of Quantum …, 1970 - ieeexplore.ieee.org
Three-wave parametric interactions are studied in media exhibiting group-velocity dispersion.
Under certain conditions these interactions may be described by the same equations that …

Ultrasonic spin echoes

NS Shiren, TG Kazyaka - Physical Review Letters, 1972 - APS
Generation and detection of ultrasonic spin echoes (phonon echoes) and of ultrasonically
induced rf magnetic field spin echoes are reported. With the latter, signal-to-noise …

Effects of 9.2-kMc/sec ultrasonics on electron spin resonances in quartz

EH Jacobsen, NS Shiren, EB Tucker - Physical Review Letters, 1959 - APS
We have observed the reduction in amplitude of electron spin resonances at 9. 2 RMc/sec
caused by ultrasonic vibrations in thesame frequency range. Measurements were made on …
