Three-body calculation of the structure ofΛ9Be

Faddeev calculations for theΛ9Be spectrum

“…Thus new classification for peaks measured in the (π + ,K + ) experiments [16] is given. This result improves previous calculations of the 9 Λ Be spectrum [14]. It is shown that the spectral properties of 9 Λ Be can be classified as an analog of 9 Be spectrum with the exception of several "genuine hypernuclear states".…”

“…Additionally our model well reproduces the experimental data for excitation energies of 9 Λ Be low-lying levels. Thus new classification for peaks measured in the (π + ,K + ) experiments [16] is given.…”

“…In the present work we renew the theoretical results [16] for energy of the 9 Λ Be resonances using the α + α + Λ cluster model. Mathematical basis of our calculations are the configuration space Faddeev equations [17].…”

“…Long time interest to the 9 Λ Be hypernucleus can be explained by usefully applying this system in the hyperonnucleon interaction studies (in particular, for the spin-orbit component of this interaction) [1][2][3][4][5].…”

“…The bound states have been studied within the α + α + Λ model in a number of works [2,3,[5][6][7][8][9][10][11][12]. Nevertheless, theoretical studies for resonance states of 9 Λ Be in the cluster model are limited by qualitative description of the 9 Λ Be spectrum [3,[13][14][15].…”
