Lecture 6: Continuum Opacity and Stellar Atmospheres
... The HI atom can also be ionized from any excited state, as well, in which case less energy is required. For example, an HI atom in the n=2 state is already at a level of over 10.x ev above ground so it only requires an additional 3.x ev to ionize it. This requires a photon of 3646 angstroms or short ...

Energy loss of deuterons in 3He gas: a threshold effect
... threshold effect has been discussed for the stopping power of protons in Ne gas 14, however these theoretical studies led to an electronic stopping power which depended on the square of the projectile velocity, i.e. no sharp threshold was predicted. Similar arguments apply to 1517, where non-res ...

If the star has a significant amount of dense core, the first stage nuclear fusion proceeds as described, but before attaining the critical temperature for the second-stage fusion, it crosses the critical density, and so the second-stage fusion does not happen. ...

Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
