At sufficiently high supersaturation, condensation does occur. The kinetic process leading to the collapse of a supersaturated state is termed nucleation and one distinguishes two types of nucleation. Spontaneous, arising without external influence and foreign, initiated by some external agent (dust, ions, etc.) [TRUNCATED]en-USBased on investigation of the BU Libraries' staff, this work is free of known copyright restrictions.Thesis/Dissertation
