给出了氢氦碰撞对（H2-He）的吸收光谱的理论估计。考虑的温度范围是从18到7000 K。由此产生的光谱，即使在小型计算机上也可以在几秒钟内计算出来，与目前已知的实验室测量结果非常吻合，并且可以可靠地推断出更高的温度和更低的温度，以及更高的频率。这项工作对外行星和某些低温恒星的大气建模很有意义，这些恒星在光谱的近红外区域含有中性分子氢和氦。38引用。
Theoretical estimates are given of the absorption spectra of collisional pairs of hydrogen and helium (H2-He). The range of temperatures considered is from 18 to 7000 K. The resulting spectra, which can be computed in seconds even on small computers, are in close agreement with presently known laboratory measurements and extrapolate these dependably to higher as well as to lower temperatures, and to higher frequencies. This work is of interest for the modeling of the atmospheres of the outer planets and certain cool stars that contain neutral molecular hydrogen and helium in the near-IR region of the spectrum. 38 references.
