Cellulose nitrate; chemical etching; activation energy; track length; response curve

Sample of cellulose nitrate (Russian) is exposed to₁₈⁴⁰Ar ions. The bulk etch rate has been studied at different etching temperatures and the activation energy for bulk etch rate has been calculated. The etched track lengths are measured for different etching times. The energy loss rate and range of₁₈⁴⁰Ar ions in CN(R) is also calculated. The critical threshold value for etchable track in CN(R) is determined by comparing the theoretical and experimental values of track length. The response curve of CN(R) is also presented.
