Studium transportu látek ve stoncích rostlin
… jako první 180° impulz následovaný 90°. U metody Hahn echo (měření efektivního relaxačního času T2*) je přiveden 90° impulz. Pro všechny metody je výsledný signál po skončení děje zachycen v příjmací cívce.

Applications of unilateral NMR in nondestructive testing
… successfully with relaxometric analysis with Hahn, CPMG and MQ pulse sequences. Besides the detection of voids in the sample, agglomerates have also been discovered with the NMR imaging technique in silicone as well as natural rubber. The results obtained with the NMR imaging experiments …

Studio multiscala degli stati elettronici e di spin indotti da difetti di punto in semiconduttori a banda larga e prospettive per le tecnologie quantistiche
… quindi il Free Induction Decay e la sequenza Hahn-echo degli impulsi di controllo sullo spin elettronico che interagisce con il bagno di spin nucleari. Facciamo luce sul fenomeno Electron Spin Echo Envelope Modulation e sull'effetto di decoerenza mediante la teoria Cluster Correlation …

A tale of two interfaces: photons and spins linked by a solid-state artificial atom
… probe its coherence via free induction decay and Hahn-echo spectroscopy. The scientific insights and technical knowledge gained from this work could enable the construction of a quantum dot system consisting of a qubit (an electron spin) and a high-fidelity, in situ quantum memory (the ensemble of …

NMR of elastomers and biological tissues
… Magic Sandwich), which scan the dipolar magic echo shape with the Hahn echo, was developed. Using this method the residual second and fourth van Vleek moments, which are more sensitive to cross-link density, were measured, model free, without the interference originated from static and …
