Metastable superpositions of ortho- and para-Helium states
نویسنده
چکیده
We analyze superpositions of orthoand para-Helium states, considering the possible existence of stationary and metastable states in the system. In particular, the metastable superposition of 1s2s ortho and para states seems to be accessible to experimental scrutiny. PACS: 03.65.-w; 32.30.-r

Quantum rotation of ortho and para-water encapsulated in a fullerene cage.
Inelastic neutron scattering, far-infrared spectroscopy, and cryogenic nuclear magnetic resonance are used to investigate the quantized rotation and ortho-para conversion of single water molecules trapped inside closed fullerene cages. The existence of metastable ortho-water molecules is demonstrated, and the interconversion of ortho-and para-water spin isomers is tracked in real time. Our inve...
متن کاملDesign of the Reactor, Selection of Catalyst for Ortho to Para Hydrogen Conversion and Preliminary Design of Cryogenic System for its Liquefaction
Hydrogen is an unusual substance in that its molecule exists in two forms, known as ortho and para, with markedly different properties. Energy level of the ortho molecule is higher than para, therefore, the latter is employed for industrial purposes. Consequently, for a high conversion of ortho to para hydrogen a catalyst reactor must be employed. Therefore, one of the main obj...
متن کاملSeparation of water into its ortho and para isomers.
Polyatomic molecules can exist as nuclear spin isomers. For example, the ortho and para hydrogen spin isomers are characterized by different values of specific heat, boiling point, heat of vapor formation, and so forth (1). Hydrogen has been the only substance whose spin modifications are well studied and available for practical use. Like H2, a water molecule also has two alternative orientatio...
متن کاملTheoretical studies on the electronically excited states of helium clusters
The vertical excited states of small helium clusters were calculated using configuration interaction singles (CIS) and the character of the states was determined from studying the attachment and detachment densities [2]. It was found that in the n=2 manifold of excited states the cluster excitations could be interpreted in terms of superpositions of atomic like states and good agreement with ex...
متن کاملAuger–dominant metastable states in the antiprotonic helium atom
Auger dominant metastable states in the antiprotonic helium atoms are studied by using the Complex Coordinate Rotation method. Relativistic corrections for the bound electron related to the Breit interaction have been calculated using CCR wave functions. Higher order relativistic and QED effects have been included into consideration to get precise theoretical values for transition frequencies.
