How can we determine if a jet gas flow is an isentropic flow?

I need to analyse experimental results of an Argon jet coming out from a reservoir with stagnation pressures of 1-5 bar, through a converging nozzle and into a vacuum chamber of 10^(-4) torr. I...

Does anybody know of a density dip in the axis of symmetry in a free jet expansion and the cause for it?

In a reconstruction of the density profile of an atomic gas jet emanating from an axis-symmetric converging microscopic nozzle, we got from the Abel inversion of some slices a dip in the density...

Can cylindrical nozzles produce microscopic supersonic gas jets?

Regarding gas jets for laser interactions, such as generation of high harmonics - I've seen articles that discuss nozzle designs for producing supersonic gas jets. Those articles always discuss a...

Is there a robust implementation(preferably in Matlab) of Abel inversion for tomographic reconstruction of axially symmetric objects?

I need to perform tomographic reconstruction of a gas jet. The jet assumed to have a circular symmetry so only a single projection (in one angle) of the jet was taken for each height along the...

What are the properties of the density distribution in atomic gas-jets ?

I'm looking for articles/books that discuss the properties of the density distribution in atomic gas-jets, in particular which are used for high harmonic generation. I'll appreciate if you can...

What are the quantum numbers l and m of the first ionized electron from an Argon atom?

the ionization probability as given by A. M. PERELOMOV, V. S. POPOV, and M. V. TERENT'EV in their article "IONIZATION OF ATOMS IN AN ALTERNATING ELECTRIC FIELD", or by Gennady L. Yudin and Misha...

Does HHG require specifically ionization by tunneling or do other ionization types also allow the generation of HH?

I'll appreciate if you can give me a reference discussing this point.

Can someone show me the derivation to the width of the potential barrier for tunneling of an electron in the presence of strong EM wave?

can someone please show me the derivation to the width of the potential barrier w=Ip/(e*E), where Ip is the ionization enery, for electron tunneling in the presence of strong electronmagnetic...
