About Expediency of Creation Compile Catalogue of Spectrophotometric Standards

“…The explicit formula for calculating the cross section of the capture reaction can be found, for example, in Ref. [10,11]. It is worthwhile noticing that the quadrupole transitions connect the ground 1 + state with three states of the continuous spectrum, namely, J π = 3 + , J π = 2 + and J π = 1 + .…”

Resonance structure of $^{8}$Be with the two-cluster resonating group method

“…Nucleus 8 Be is a very interesting object which attracts large attention from various theoretical and experimental methods. This nucleus has no bound states but it has a reach collection of resonance states.…”

“…The low-energy part of resonance states belongs to the two-cluster continuum of two interacting alpha particles. There are three resonance states 0 + , 2 + and 4 + , which are considered as a rotational band of the 8 Be nucleus. The 0 + resonance state is a very narrow resonance state with the energy 0.092 MeV above the α + α decay threshold.…”

“…In the present paper we are going to study structure of 8 Be and pay main attention to wave functions of resonance states. For this aim we employ a specific variant (version) of the resonating group method (RGM) which was formulated in Refs.…”

“…The matrix form can be applied to study both bound and resonance states since corresponding boundary conditions well-known in coordinate space were transformed into discrete, oscillator representation. At present time, the algebraic version of the resonating group method is very efficient and popular tool to study dynamics of two-cluster systems ( [4,5,6,7,8]), and three-cluster systems as well ([9, 10, 11, 12]).…”
