Spectroscopy of the 10Li isotope in stopped pion absorption reactions on a 14C radioactive target

Selective population of unbound states in 10Li

“…This placed the first measured unbound state at 0.8 ± 0.25 MeV decay energy [8]. The next measurement was made 15 years later [9] and since then, there have been many measurements of energies of the continuum structure of 10 Li [4,5,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]34].…”

Mechanisms of sequential particle transfer and characteristics of light neutron-excess and oriented nuclei

“…Experimental data are borrowed from [80]. DWBAFR, which is based on a graphical representa tion, and showed that the expression obtained this way coincides with (56), up to phase factors and normal ization. Expression (56) contains coherent summa tions over the momenta of an intermediate system.…”

“…An expression (56) was used in previous sections to calculate the matrix elements of quadrangle mecha nisms. This expression is analytically obtained in the case of the four body approximation for the channels (3,1).…”

“…An expression for the matrix element of the pro cess, illustrated by a diagram with multidirectional internal lines, is analogous to (56) up to replacement of summation indices and decay widths of nuclei.…”

“…Detailed experimental studies of the spectroscopy of hydrogen and lithium isotopes with large (about 4-5) excess of neutrons were undertaken in [50][51][52][53][54][55][56]. In the experi ments [50][51][52][53], conducted in an inverse geometry, certain shapes of spatial distribution of the nucleons in neutron excess nuclei were identified by using com plex correlation techniques.…”
