Abstract

Capture coefficients and reflected flux distributions have been measured for nitrogen molecular beams impinging on solid nitrogen surfaces. For a beam intensity of 1.53×10¹⁶ molecules/sec cm² and incident energies from 0.44 to 0.76 eV, the capture coefficient was found to decrease with increasing angle of incidence as measured from the surface normal. The angle of maximum reflected intensity was approximately 75° from the surface normal and independent of incident angle and energy. Transient effects were observed for surfaces without a previous cryodeposit.
