Gamma transitions in 60Ni following the β+ decay of 60Cu (II)

Isobaric analogue states excited in the59Co(p, ?)60Ni reaction

“…The lowest nine levels in 6~ have been investigated lately in three experiments by van Patter and Rauch [14] and Ronsin et al [18]. Their results are in good agreement with our results and are also presented in Table 2.…”

“…From this level there is a 993 keV transition to the 2625 keV level. This transition has also been observed by van Patter and Rauch [14].…”

“…The intensity ratio of these transitions was measured to be 40:60. Both Ronsin et al [18] and van Patter and Rauch [14] have observed a transition to the 3 185 keV level with an energy of 739 keV. In our spectra we have seen a double peak, where one of the components has an energy of 740 keV, which gives too great an energy for this level compared with the energy given by the sums of other gamma rays from this level.…”

“…These energies are given in Table 2 together with estimated errors founded on how well-defined the gamma-ray peaks are, and on how well the different sums of the energies of the branches match. The branching ratios together with those of van Patter and Rauch [14] and Ronsin et al [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] are given in Table 2. The errors here are also founded on how well-defined the gamma-ray peaks are and on the agreement between the decay schemes obtained at the different proton excitation energies.…”

“…These are supposed to be the isobaric analogues of the ground state and the first excited states in 6~ We have studied the gamma-ray decay of these levels and also of levels close to these. The excited levels in 6~ have previously been studied by (p, p'), (p, t), (d, p), (3He, d) and (~, t) experiments [9][10][11][12] and decay, J'~ and lifetimes by [1 + decay of ~~ and by (P,P'7) and (3He, dT) experiments [13][14][15][16][17][18].…”
