Superheated drops of R114 - as a neutron spectrometer

The basic principle that has been used in the application of superheated dr ops in neutron spectrometry is its dependence of threshold energy of nuclea tion on temperature. In the present work, superheated drops of R114 suspend ed in a visco-clastic gel were irradiated at different temperatures by neut rons obtained from an Am-241-Be source. The temperature of the detector was converted to the energy of the incident neutrons following the method deve loped by us to unfold the neutron energy spectrum. The threshold energy obt ained by us agrees well with other results obtained using monochromatic neu tron sources, clearly demonstrating the validity of our principle of spectr ometry.
