  Superheated drops are known to vaporise when exposed to energetic nuclear
radiation since the discovery of bubble chamber. As the degree of superheat
increases in a given liquid, less and less energetic neutrons are required to
cause nucleation. This property of superheated liquids are being utilised to
develope the neutron spectromer. A new principle of neutron spectrometry using
Superheated liquid are developed and the developed principle has been tested by
Am-Be neutron source.
