You know the cross-section is perpendicular to the x-axis. A width dx, then, should given you a cross-section with volume, and you can integrate dx and still be able to compute the area for the cross-section.

WebWe then make some argument showing cross section of a bound-bound transition can be seen as power (through Larmor's formula) divided by Poynting vector flux. If you do the … WebBound-Free Absorption Bound-free absorption is photoionization from the point of view of the radiation field: a photon is removed from circulation, being used to eject an electron …
WebThe opacity due to free-free, bound-free, and bound-bound electronic transitions can be approx-imated with the so called “Kramers formula”: κK ≈ 4×1025 (1+X) (Z +0.001) ρ … Webfactor. The form of the bound-free cross section is an abrupt rise at ωn followed by a decline that is ∼ ω−3 near threshold, but ∼ ω−7/2 far from the threshold. Incidentally, in practice the ISM has bound-free edges from many different elements and …

You have the area bounded by x = y, x = − y, and y = 1. So we have our bounds of integration are ( 0, 1). The side length of the square for each y are 2 y. Our volume is the sum of several squares with infinitesimal width (dy). We have ∫ 0 1 ( 2 y) 2 d y = 2 Share Cite … blackwood hampshireWebFroissart bound.
