Description
The QRPA approach is a powerful method that enables to predict collective nuclear excited states both for low and high energies. It has indeed been successfully used to describe giant resonances, and it has been shown to enable a reasonable description of low energy collective states. The extension of the approach, performed to study the influence of QRPA states couplings on decay lifetimes in Gadolinium isotopes has paved the way to compute electromagnetic transitions between excited QRPA levels. Since then, a new approach for gamma strength function determination involving gamma emission between excited states in addition to traditional transitions between ground state and excited states is under investigation. A recent development has also shown that the same QRPA levels could be used as a starting point for a new level density model. I will describe these two ways of exploiting QRPA predictions, to produce within a coherent framework nuclear level densities and gamma strength functions.
