Fragmentation angular distributions

A typical fission fragment angular distribution for a heavy-ion-induced fission reaction is shown in Figure 11.21. As one can see, the fragments are emitted...

Fission fragment angular distributions for the 4.86,4.91, and 4.97 resonances in compared to the theoretically calculated curves assuming different K values for the rotational bands. Based on Krasznahorkay et al. (1998)... 

It is well known that the electron-impact ionization mass spectrum contains both the parent and fragment ions. The observed fragmentation pattern can be usefiil in identifying the parent molecule. This ion fragmentation also occurs with mass spectrometric detection of reaction products and can cause problems with identification of the products. This problem can be exacerbated in the mass spectrometric detection of reaction products because diese internally excited molecules can have very different fragmentation patterns than themial molecules. The parent molecules associated with the various fragment ions can usually be sorted out by comparison of the angular distributions of the detected ions [8]. 

The angular distributions for the slow and fast 0(3P2) fragments have been determined separately. The division between slow and fast fragments corresponds to the relative minimum in the 0(3P2) speed... 

The angular distributions of the 0(3P2) fragments show the degree of correlation between the product recoil velocity (v) with the electric vector of the dissociating light and are typically characterized by the lab frame anisotropy parameter (/ ) given in the equation,52,53...
