A low-energy transfer, or low-energy trajectory, is a route in space that allows spacecraft to change orbits using significantly less fuel than traditional transfers. [ 1 ] [ 2 ] These routes work in the Earth – Moon system and also in other systems, such as between the moons of Jupiter .
The possible screw axes are: 2 1, 3 1, 3 2, 4 1, 4 2, 4 3, 6 1, 6 2, 6 3, 6 4, and 6 5. Wherever there is both a rotation or screw axis n and a mirror or glide plane m along the same crystallographic direction, they are represented as a fraction n m {\textstyle {\frac {n}{m}}} or n/m .
In diffusion theory, radiance is taken to be largely isotropic, so only the isotropic and first-order anisotropic terms are used: (, ^,) = =, (,), (^) where n, m are the expansion coefficients. Radiance is expressed with 4 terms: one for n = 0 (the isotropic term) and 3 terms for n = 1 (the anisotropic terms).
As a woodland plant, myoga has specific shade requirements for its growth. It is frost-tolerant to −16 °C (3 °F), and possibly colder. [3] Three variegated cultivars are known: 'Dancing Crane', 'Silver Arrow' and 'White Feather'. They are less cold-hardy than unvariegated plants. [3]
In physics, and especially scattering theory, the momentum-transfer cross section (sometimes known as the momentum-transport cross section [1]) is an effective scattering cross section useful for describing the average momentum transferred from a particle when it collides with a target. Essentially, it contains all the information about a ...

The intense blue color of Prussian blue is a consequence of an intervalence charge transfer band. In chemistry, intervalence charge transfer, often abbreviated IVCT or even IT, is a type of charge-transfer band that is associated with mixed valence compounds. It is most common for systems with two metal sites differing only in oxidation state.
