Possibilities for gamma-ray stimulated emissionexperiments

We show that gamma-ray stimulated emission experiments are comparatively easy and inexpensive. The registration of a double- (N_2γ/N_γ) and a triple-energy peak (N_3γ/N_γ) is possible and the relation between their intensities permits the calculation of the recoilles factor f_s (stimulated) and making a conclusion about constructing a working gamma-ray laser. This revised version was published online in August 2006 with corrections to the Cover Date.
