The odd isobars

A = 5 Fig. 63. Phase shift analysis of the (pa) and (na) scattering experiments (Fig. 28) indicates that the ground and first excited states of these nuclei form an inverted doublet, Pij. These states are formed by addition of a -nucleon to the alpha particle core and if the -phase shifts are calculated from resonance theory (Adair ), the reduced widths obtained are near to the single particle value. There is no distinction in this case between LS and // coupling. The simplicity of the system suggests also a direct treatment in terms 

The 2 state corresponding to the 5-wave scattering phase shift has not been identified and is probably at an excitation of more than 20 MeV [19], The single particle levels 

The spin and parity assignments shown are based on the analysis of resonance reactions for the 7 MeV levels these levels have comparable reduced widths. The 6 MeV levels must be formed by s-nucleons if the large thermal neutron scattering length, and the lv proton absorption in Li are to be simply explained

The parameter ajK may also be deduced from the intermediate-coupling calculations of reduced width, beta-decay lifetime, and M1 transition probability given by Lane . Of these quantities the reduced width is most sensitive to
