17B (93TI07)(Not illustrated) 17B was observed in the 4.8 GeV proton bombardment of Uranium: it is particle stable and its ground state probably has Jπ = 3/2- (74BO05, 86AJ04) in agreement with the shell model (92WA22). It has been observed in several heavy ion reactions (87GI05, 88DU09, 88SA04, 88TA1N, 88WO09, 89LE16). The atomic mass was measured to be 42.82 ± 0.80 MeV (87GI05), 43.62 ± 0.17 MeV (88WO09), and 43.90 ± 0.23 MeV (91OR01), which compare well with the predicted mass of 43.31 ± 0.50 MeV (88WA18). See also (86AN07). The half life has been measured to be T1/2 = 5.3 ± 0.6 msec (88SA04), 5.08 ± 0.05 msec (88DU09), and 5.9 ± 3.0 msec (91RE02). Beta-delayed multi-neutron emission has been observed and branching ratios have been measured (88DU09, 89LE16, 91RE02).
A model of 17B considered as a three-body system composed of a
15B core and two outside neutrons was studied by (90RE16).
The binding energy and radius were calculated. Shell model interactions
in the cross-shell model space connecting the 0p and 1s0d shells were
applied in the A = 15 - 20 Boron isotopes by (92WA22).
