The cross section and frequency shift of the magnetic resonance line for the spin exchange are calculated for a collision of lithium and cesium atoms in the ground state. The calculation was carried out on the basis of data on the singlet (X1Sigma+) and triplet (a3Sigma+) interaction potentials of the 7Li133Cs dimer. The transfer from the energy to the temperature dependence of the real and imaginary parts of the complex cross sections for a spin exchange allows us to obtain information both the broadening of the magnetic resonance line of the atoms under study and the frequency shift of the magnetic resonance upon their collision.

AbstractSpin-exchange cross sections and the magnetic-resonance frequency shift in collision of lithium and potassium atoms in the ground state have been calculated for the first time. The cross sections are calculated based on the data on the singlet ( $$X{}^{1}{{\Sigma }^{ + }}$$ ) and triplet ( $$a{}^{3}{{\Sigma }^{ + }}$$ ) interaction potentials of ^39K^7Li dimer. A passage from the energy dependences to the temperature ones of the real and imaginary parts of the complex spin-exchange cross section yields information about both the broadening of the magnetic resonance line of the atoms under study and the magnetic-resonance frequency shift in their collision.

AbstractA strong limitation of nuclear magnetic resonance is its low inherent sensitivity that can be overcome by using an appropriate hyperpolarization technique. Presently, dynamic nuclear polarization and spin-exchange optical pumping are the only hyperpolarization techniques that are used in applied medicine. However, both are relatively complex in use and expensive. Here we present a modification of the signal amplification by reversible exchange (SABRE) hyperpolarization method – SABRE on stabilized Ir-complexes. A stabilized Ir-complex (here we used bipyridine for stabilization) can be hyperpolarized in a wide range of magnetic fields from a few μT upto 10 T with
