Energy levels of some Zn, Ga, As, Se and Br isotopes from (p, n) reactions

In-beam study of excited states in80Br

“…The properties of the positive-parity states point to a decrease of the effective nuclear deformation with increasing neutron number similarly as deduced for the doubly-even Kr nuclei [11]. In order to study the properties of the (7~g9/2, Pg9/2) multiplet for higher neutron numbers we initialized an in-beam investigation of the doubly-odd nucleus 8~ Low-spin states (I_<__ 5) of S~ have previously been investigated via the radioactive decay of the 5-isomer at 85.84 keV [12], in neutron transfer reactions of the type (d,p) [13] and (p, d) [14], in the (p, n) charge exchange reaction [15], in the (p, n7) reaction [16] and in the thermal neutron capture reaction [17]. As a result of the (n, 7) study a very complex level scheme has been proposed including 18 levels below an excitation energy of 500 keV.…”

Study of the level structures of80Br and82Br using the thermal neutron capture reaction

“…A comparison of the present results with the level sequence observed in the (d,p) reaction [1], the (p, ny) reaction [2,32] is given in Table 4 in a similar manner to what was done for a~ above.…”

“…As primary transitions are expected to be dipole in nature, levels with spin values J=0, 1, 2 and 3 should be populated directly. A comparison of the present results with the level sequence observed in the (d, p) reaction [1], the (p, n) and (p, nT) reactions [2,3,32] is given in Table 2.…”

“…This paper reports on a study of the levels of the doubly odd nuclei of 8~ and 82Br. The low-lying excited states of S~ and SZBr have been previously studied by the (d,p) [1] stripping reaction and (p,n) [2,3] charge-exchange reaction. In spite of these efforts, 0340-2193/78/0286/0107/$02.60 Do Huu Phuoc et ai.…”
