For eight HCO+ rotational transitions we compare semiclassical and quantum calculations of the line broadening and shift induced by collisions with argon and helium atoms. A detailed analysis of the results allows better insights into the problem of the accuracy of the semiclassical model commonly used in most line shape studies.

Abstract
For eight HCO+ rotational transitions we compare semiclassical and quantum calculations of the line broadening and shift induced by collisions with argon and helium atoms. A detailed analysis of the results allows better insights into the problem of the accuracy of the semiclassical model commonly used in most line shape studies.File in questo prodotto:
