LADP-3 Microwave Electron Spin Resonance Totoga
E faʻaigoaina le faʻaaogaina ole eletise eletise e faʻaigoaina ole electron paramagnetic resonance, lea e faʻatatau ile faʻaaliga ole resonance suiga ile va ole malosiaga maneta ole eletise ole uila eletise i le taimi o le maneta peʻa e aʻafia ile galu ole eletise fesoʻotaʻiga masani ile malae maneta. Lenei vaʻaiga mafai ona maitauina i paramagnetic mea ma le pauna viliina maneta taimi maneta (ie tuʻufaʻatasia o aofia ai electron faʻaopoopoina). O le mea lea, electron spin resonance o se taua metotia e iloa ai le faʻaaogaina electron i mea ma a latou fegalegaleaiga ma siosiomaga atoms, ina ia maua ai le faʻamatalaga e uiga i le microstructure o le mea. O lenei metotia e maualuga le maaleale ma iugafono, ma e mafai ona faʻaaogaina e auiliili ai mea i auiliiliga e aunoa ma le faʻaleagaina o le faʻataʻitaʻiga fausaga ma leai se faʻalavelave i vailaʻau tali atu. I le taimi nei, e lautele faʻaaogaina i le suʻesuʻega o fisiki, kemisi, biology ma vailaʻau.
Faʻataʻitaʻiga
1. Suesue ma faʻalauiloa electron spin resonance phenomena.
2. Fua fua Lande's g-vaega ole DPPH faʻataʻitaʻiga.
3. Aʻoaʻo pe faʻafefea ona faʻaaoga masini faʻaeletise i le EPR system.
4. Malamalama i le galu tu i le suia o resonant umi pu ma fuafua galu galu.
5. Fuataga tu galu malae tufatufaina i resonant ana ma fuafua galu galu gelombang.
