Using a high resolution Si (Li) detector with the help of computer program for spectrum analyzing, we have decomposed these lines into its components. Fig. 1 shows the X-ray and the 26.35 keV Another example is the alpha decay of 241Am to form 237Np; which is followed by gamma emission. In some cases, the gamma emission spectrum of the daughter nucleus is quite simple, (e.g. 60Co/60Ni) while in other cases, such as with (241Am/237Np and 192Ir/192Pt), the gamma emission spectrum is complex, revealing that a series of nuclear energy levels exist.

This is a complicated decay with many possible modes--there are one or more gamma associated with every alpha line (except, perhaps the highest energy one). It is essentially impossible to compute the photon spectrum from first principles; they must be measured and doing so well is a delicate experiment.

Decay scheme The scheme of 241Am decay is rather complex. It contains more than forty excited levels in 237Np populated by alpha- and gamma-transitions (1995Ak01). For high levels the decay scheme is not completed as great number of observed gamma transitions are not placed in the level scheme and some expected gamma transitions have not The decay process continues until stable bismuth is formed. The radiation from the decay of americium-241 and its daughters is in the form of alpha particles, beta particles, and gamma rays.

This results in a very complex energy spectrum.
