چکیده

Buffer gas cooling is used to trap NH molecules with 1/e lifetimes exceeding 20 s. Helium vapor generated by laser desorption of a helium film is employed to thermalize 10 molecules at a temperature of 500 mK in a 3.9 T magnetic trap. Long molecule trapping times are attained through rapid pumpout of residual buffer gas. Molecules experience a helium background gas density below 1× 10 cm−3.

Electrostatic trapping of metastable NH molecules

We report on the Stark deceleration and electrostatic trapping of NH (a ∆) radicals. In the trap, the molecules are excited on the spin-forbidden A Π ← a ∆ transition and detected via their subsequent fluorescence to the X Σ ground state. The 1/e trapping time is 1.4 ± 0.1 s, from which a lower limit of 2.7 s for the radiative lifetime of the a ∆, v = 0, J = 2 state is deduced. The spectral pro...

Accumulating NH radicals in a magnetic trap

Recently, we have succeeded in trapping neutral dipolar molecules in an electrostatic trap and in a storage ring exploiting the interaction of these molecules with time-varying inhomogeneous electric elds. To be able to study molecular interactions and collective e ects in these trapped cold molecular gases, with the experimental realization of molecular Bose-Einstein condensation and coherent ...

The Study of Improvement of Dispersive Soil Using Magnetic Field

In this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. The reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. The results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...

Stern-Gerlach deflection of field-free aligned paramagnetic molecules.

The effects of laser-induced pre-alignment on the deflection of paramagnetic molecules by inhomogeneous static magnetic field are studied. Depending on the relevant Hund's coupling case of the molecule, two different effects were identified: either suppression of the deflection by laser pulses (Hund's coupling case (a) molecules, such as ClO), or a dramatic reconstruction of the broad distribut...

Loss of molecules in magneto-electrostatic traps due to nonadiabatic transitions

We analyze the dynamics of a paramagnetic, dipolar molecule in a generic “magneto-electrostatic” trap where both magnetic and electric fields may be present. The potential energy that governs the dynamics of the molecules is found using a reduced molecular model that incorporates the main features of the system. We discuss the shape of the trapping potentials for different field geometries, as ...
