Answering the Question as Asked The raw data is available from a unreasonable and unmanageable slew of papers published in endless venues over the last upteen decades. Ouch. The processed data is available in the form of ENDFs (evaluated nuclear data files) maintained by several agencies (i.e. these is a Japanese adgency that maintains the JENDFs), but ...

Are you using the Apex-Gamma software? If so, a fitted singlet is a line the software has identified as being a single distinct line rather than a peak in a region where there are multiple overlapping lines. As I recall, Apex-Gamma identifies lines that are overlapping by $M$ or $m$ (presumably for multiplet).

That means that the peaks could be fit with single Gaussian, the simplest fit. They did not have to fit as a doublet (two lines close together). Ortec has a technical paper on line at Deconvolution of Gamma-Ray Peak Doublets as a Function of Peak Separation and Relative Amplitude

Background There is a good reference1 on the physics of sound/shock waves in solids (look at Chapter XI). I found the following (on page 688) very interesting and relevant to your question: In a solid or liquid, a shock wave with a strength of even a hundred thousand atmospheres is regarded as weak. Such a wave differs little from an acoustic wave: it ...

The explosive material being tested is typically in a rod or puck shape whose radius is considerably smaller than the impactor and anvil. The impact generates a shock wave through the material sample. Since I am using an Eulerian code to simulate this, I need to know the pressure of the resulting shock wave in the material. Is there a way to ...
